  1. Rate constants in the following reaction are Reaction 1 :

$$ A \xrightarrow{\text { Catalyst } 1} P_1, k_1=1 \mathrm{~s}^{-1} $$

Reaction 2 :

$$ A \xrightarrow{\text { Catalyst } 2} P_2, k_2=0.1 \mathrm{~L} \mathrm{~mol}^{-1} \mathrm{~s}^{-1} $$

Reaction 3 :

$$ A \xrightarrow{\text { Catalyst } 3} P_3, k_3=0.01 \mathrm{~L} \mathrm{~mol}^{-1} \mathrm{~s}^{-1} $$

A

$r_1=\frac{r_3}{100}, r_2=\frac{r_3}{10}$

B

$r_1=\frac{r_2}{10}, r_2=\frac{r_3}{10}$

C

$r_1=100 r_3, r_2=\frac{r_3}{10}$

D

$r_1=10 r_2, r_3=\frac{r_2}{10}$
