MDCAT Chemistry Chapter 8 online mcq test with answers for chapter 8 (Reaction Kinetics)

In chapter 8 of chemistry, the students have to focus on the theoretical and reactions portions. The syllabus includes both portions, and the questions will be asked in the entry test accordingly. The candidates preparing for the test should consider all the topics and be prepared for the entry test to get good marks in the MDCAT. The students can get the online MCQs by going through this portal. The main reason for offering the MCQs is to assist the students during the preparatory phase of the test. After the preparation of the specific chapter, the students must solve the MCQs of that chapter. The students can also get the MCQs of all the other chapters of chemistry as well from this platform. To get more information about the MDCAT preparation, keep in touch with us.

In this topic,Student should be able to:

a) Explain, in terms of rates of the forward and reverse reactions, what is meant by a reversible reaction and dynamic equilibrium.

b) State Le Chatelier’s Principle and apply it to deduce qualitatively the effects of changes in temperature, concentration or pressure, on a system at equilibrium.

c) Deduce whether changes in concentration, pressure or temperature or the presence of a catalyst affect the value of the equilibrium constant for a reaction.

d) Deduce expressions for equilibrium constants in terms of concentrations; Kc, and partial pressures; Kp

e) Calculate the values of equilibrium constants in terms of concentrations or partial pressures from appropriate data

f) Calculate the quantities present at equilibrium, given appropriate data.

g) Describe and explain the conditions used in the Haber process.

h) Understand and use the Bronsted-Lowry theory of acids and bases.

i)Explain qualitatively the differences in behaviour between strong and weak acids and bases and the pH values of their aqueous solutions in terms of the extent of dissociation.

j) Explain the terms pH; Ka; pKa; Kw and use them in calculations.

k) Calculate [H+(aq) and pH values for strong and weak acids and strong bases.

l) Explain how buffer solutions control pH.

m) Calculate the pH of buffer solutions from the given appropriate data.

n) Show understanding of, and use, the concept of solubility product, Ksp.

o) Calculate Ksp from concentrations and vice versa.

p) Show understanding of the common ion effect.
