The main difference between a catalyst and an enzyme is:
Correct answer: C. Catalysts are inorganic while enzymes are organic in nature
- A. Enzymes are sharp in action than catalyst
- B. Catalysts are used in larger concentration than enzymes
- C. Catalysts are inorganic while enzymes are organic in nature
- D. Enzymes need pH while catalysts do not need something
Explanation
Catalyst: Substance that increases the rate of a chemical reaction without being consumed. Can be organic or inorganic.Enzyme: A biological catalyst, always organic (proteins or RNA), highly specific, and works under mild conditions (temperature, pH).Main difference: enzymes are organic molecules (proteins or RNA), while many chemical catalysts are inorganic.

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.
