The catalyst in the formation of ester from alcohol and a weak acid is?
Correct answer: D. A mineral acid
- A. A base
- B. Palladium
- C. Nickel
- D. A mineral acid
Explanation
Esterification is the process of combining an organic acid such as carboxylic acid with an alcohol to form ester. The catalyst used is a concentrated sulphuric acid which is a strong mineral acid Options A , B & C are incorrect.

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.
