Question

Which one of the following is wrongly matched?

• A. Saponification of $CH_3COOCH_3 -$ Second order reaction
• B. Hydrolysis of $CH_3COOCH_3 -$ Pseudo unimolecular reaction
• C. Decomposition of $H_2O_2 -$ First order reaction
• D. Combination of $H_2$ and $B_2$ to give $HBr -$ Zero order reaction

Answer 1

Answer: (D)

$H_2 + Br_2\rightleftharpoons 2HBr$ is a $1.5$ order reaction i.e., $K=\left[H_{2}\right]\left[Br_{2}\right]^{1/2}$
