This is the 3rd MDCAT mock test. This test will cover the following subjects and topics. This is the 3rd mock test for the Pakistan Medical Commission’s (PMC) Medical and Dental College admission examination. The exam tests knowledge of a variety of topics, including Reaction Kinetics. In this section, you will be asked questions about the rates of chemical reactions and how they are affected by various factors. Be sure to brush up on your knowledge of this topic before taking the exam!

Biology-I

Coordination and control

All living things coordinate and control their activities to stay alive and function properly. For example, animals need to coordinate their movements to find food and avoid predators, while plants need to control their water intake to prevent dehydration. coordination and control are essential for all living things.
In higher organisms, coordination and control are carried out by the nervous system and the endocrine system. The nervous system is composed of neurons that carry messages between different parts of the body. The endocrine system consists of glands (located in various parts of the body) that release hormones into the bloodstream, which act as chemical messengers to regulate functions throughout the body. Examples of these include thyroid hormone, which regulates metabolism; insulin, which regulates blood sugar levels; adrenaline, which helps with an organism’s fight-or-flight response; and growth hormone, which stimulates cell division.

Chemistry-I

Reaction Kinetics

Chemical kinetics,  as a branch of chemistry, deals with the rates at which chemical reactions take place. There are two main areas that chemical kinetics covers: reaction rate and equilibrium. The reaction rate is the speed at which a reaction takes place, while equilibrium is when all reactants and products have reached a balance in their concentrations.
Rates of reaction are affected by temperature. If you increase the temperature of a system (a test tube for example), then there will be more collisions between molecules due to the increased kinetic energy. A higher collision frequency means a faster reaction rate. Another factor that affects the reaction rate is pressure.
Pressure has less of an effect on most reactions than temperature does because it mainly influences gases, which make up only about one per cent of any typical mixture (as opposed to solids or liquids). The amount of pressure applied doesn’t change the number of molecules or particles but rather changes how much space they occupy so they bump into each other more often.

Thermochemistry

The study of thermochemistry helps us understand how energy is transferred and used by chemical reactions. In this mock test, we’ll focus on understanding how to calculate enthalpy, entropy, and Gibbs’s free energy. By the end of this test, you should be able to correctly answer questions about Hess’s law, bond dissociation energies, and more!

Energetics of Chemical Reactions

Chemical reactions exchange energy with their surroundings by releasing or absorbing heat. The most common type of chemical reaction is the combustion, in which the molecules in a fuel combine with oxygen from the air to release heat. Other examples include photosynthesis and the oxidation of iron to form rust. During these processes, light energy is absorbed by chlorophylls in plants or O2 in human cells, changing it into chemical energy stored as ATP. Likewise, when H2O reacts with O2 during aerobic respiration, electrons are transferred to water molecules that then become hydrogen ions (H+) and hydroxide ions (OH-). As electrons move through an electron transport chain (ETC), protons are pumped across the membrane of the mitochondria.

Physics-I

Waves

Waves can be generated in the atmosphere, oceans, and on solid ground. The types of waves depend on their location and speed of movement. For example, a surface wave is caused by wind moving across water. In the ocean, waves form because of winds blowing over water. An atmospheric wave is a result of changing air pressure as a result of weather systems or jet streams. These are called internal waves that exist inside bodies of water like lakes and oceans. They have different names depending on where they occur: thermocline for the surface waves; Mann-Higgs for those below the thermocline; internal tide for those propagating through whole volumes of water; and internal seiche for those confined to one place.

English

Use of subject-verb agreement

Subject-verb agreement Always agrees in number with the verb. The subject is singular if it refers to a single person, place, or thing. Articles and prepositions: Articles – a, an, the; Prepositions – in, on, at. Singular nouns refer to one (1) thing/person/place. Plural nouns refer to more than one (1). When you’re unsure whether a noun is singular or plural, try replacing it with either he or them. If you can replace the word with he, then use the masculine pronoun for its antecedent. If you can replace the word with they, then use the plural pronoun for its antecedent. Pronouns should agree on gender with their antecedents. A compound sentence may have two main clauses joined by a coordinating conjunction such as and, but, or, etc., but each of these main clauses must have both a subject and a verb, so it’s considered correct to separate them into two sentences that join together like parts of one sentence.

Logical Reasoning

Logical deduction

Logical deduction is the process of concluding that something is true based on the evidence. The type of logical reasoning can be called induction, which means making a conclusion based on many observations. There are also types of deductive reasoning that involve less observation and more reasoning about what must be true given what we know to be true. Both inductive and deductive logic is used in sciences such as biology, where theories are constructed to try to make sense of observations.
