Chemical Kinetics Question 29
Question: The differential rate law for the reaction $ H_2+I_2\to 2HI $ is [AIEEE 2002]
Options:
A) $ -\frac{d[H_2]}{dt}=-\frac{d[I_2]}{dt}=+\frac{1}{2}\frac{d[HI]}{dt} $
B) $ \frac{d[H_2]}{dt}=\frac{d[HI]}{dt}=\frac{1}{2}\frac{d[HI]}{dt} $
C) $ \frac{1}{2}\frac{d[H_2]}{dt}=\frac{1}{2}\frac{d[I_2]}{dt}=-\frac{d[HI]}{dt} $
D) $ -2\frac{d[H_2]}{dt}=-2\frac{d[I_2]}{dt}=+\frac{d[HI]}{dt} $
