Correct answer: B. Qc > Kc
- A. Qc < Kc
- B. Qc > Kc
- C. Qc= Kc
- D. Qc = (Kc)3
Explanation
Reversible Reactions: Reversible reactions are those that can proceed in both the forward and reverse directions. These reactions are in a state of dynamic equilibrium, where the rates of the forward and reverse reactions are equal, and the concentrations of reactants and products remain relatively constant over time.The reaction will proceed in the reverse direction when one of the following conditions is met: The concentration of products is increased. The concentration of reactants is decreased. The temperature is decreased (for some reactions, as lower temperature favors the exothermic direction).

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.

The rate constant for forward and backward reactions of hydrolysis of ester are 1 x 10^-2 and 2 x 10^-3 respectively. The equilibrium constant of the reaction is:
The reactions that occur only in one direction are known as:
The value of K.E is changed by change in temperature because:
The pH of acidic buffer increases by adding more salt in it because:
An acidic buffer solution can be prepared by mixing:
A certain buffer solution contains equal concentration of salt and acid. The Ka for salt is 10-10. The POH of the buffer is:
