MDCAT Chemistry Chapter 7 online mcq test with answers for chapter 7 (Chemical Equilibrium)

Preparing for the MDCAT is considered the critical phase in which the students must do maximum hard work to score well on the entry test. The students can take assistance from the preparation material available on this platform. The online MCQs are available here so students can solve and strengthen their preparation before the test. By taking the mock test, the students can better understand the type of questions being asked in the entry test. So the students must solve the online test and do better preparation for the test. Besides this, by taking the online test, the students can also learn how to manage their time and complete the test in a given time. For further information about MDCAT, keep in touch with us.

In this topic,Student should be able to :

a) Describe and explain redox processes in terms of electron transfer and/or of changes in oxidation number.

b) Define the terms: Standard electrode (redox) potential and Standard cell potential.

c) Describe the standard hydrogen electrode as reference electrode.

d) Describe methods used to measure the standard electrode potentials of metals or non-metals in contact with their ions in aqueous solution

e) Calculate a standard cell potential by combining two standard electrode potentials.

f) Use standard cell potentials to: i) Explain/deduce the direction of electron flow in the external circuit. ii) Predict the feasibility of a reaction.

g) Construct redox equations using the relevant half-equations.

h) State the possible advantages of developing the H2/O2 fuel cell

i) Predict and to identify the substance liberated during electrolysis from the state of electrolyte (molten or aqueous), position in the redox series (electrode potential) and concentration e.g. H2SO4(aq) and Na2SO4(aq).
