Which of these reactions occur at a moderate rate?
Correct answer: C. Hydrolysis of Ester
- A. Rusting Of Iron
- B. Fermentation of sugar
- C. Hydrolysis of Ester
- D. Chemical weathering of stone work by acid
Explanation
The acid produced in the reaction acts as a catalyst and makes the reaction faster. Thus, it occurs at a moderate speed.

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.
