Question

The decomposition of hydrogen peroxide can be slowed by the addition of acetamide. The latter acts as a/an :

• A. Detainer
• B. Stopper
• C. Promoter
• D. Inhibitor
• E. None

Answer 1

The correct option is D Inhibitor

The chemical substance added to another substance to slow down a reaction or to prevent an unwanted chemical change is called an inhibitor or negative catalyst. In the decomposition of hydrogen peroxide, unwanted chemical change can be slowed down by the addition of a small amount of acetamide which acts as an inhibitor.

Hence, option (D) is correct.
