MCQ
Which one of the following is wrongly matched
  • A
    Saponification of $C{H_3}COO{C_2}{H_5}$$-$ Second order reaction
  • B
    Hydrolysis of $C{H_3}COOC{H_3}$ $-$ Pseudo uni-molecular reaction
  • C
    Decomposition of ${H_2}{O_2}$ $-$ First order reaction
  • ✓
    Combination of ${H_2}$ and $B{r_2}$ to give $HBr$ $-$ Zero order reaction
✓

Answer

Correct option: D.
Combination of ${H_2}$ and $B{r_2}$ to give $HBr$ $-$ Zero order reaction
d
(d)

${H_2} + B{r_2} \rightleftharpoons 2HBr$ is a $1.5 $ order reaction

i.e., $K = [{H_2}]{[B{r_2}]^{1/2}}$.
