SATHEE: Chemical Kinetics Question 29

Chemical Kinetics Question 29

Question: The differential rate law for the reaction $H_{2} + I_{2} \to 2 H I$ is [AIEEE 2002]

Options:

A) $- \frac{d [H_{2}]}{d t} = - \frac{d [I_{2}]}{d t} = + \frac{1}{2} \frac{d [H I]}{d t}$

B) $\frac{d [H_{2}]}{d t} = \frac{d [H I]}{d t} = \frac{1}{2} \frac{d [H I]}{d t}$

C) $\frac{1}{2} \frac{d [H_{2}]}{d t} = \frac{1}{2} \frac{d [I_{2}]}{d t} = - \frac{d [H I]}{d t}$

D) $- 2 \frac{d [H_{2}]}{d t} = - 2 \frac{d [I_{2}]}{d t} = + \frac{d [H I]}{d t}$
