Chemical Kinetics Question 27

Question: For the reaction $ H_2(g)+I_2(g) $ ⇌ $ 2HI(g) $ , the rate of reaction is expressed as [CBSE PMT 1997; AIEEE 2002]

Options:

A) $ -\frac{\Delta [I_2]}{\Delta t}=-\frac{\Delta [H_2]}{\Delta t}=\frac{1}{2}\frac{\Delta [HI]}{\Delta t} $

B) $ \frac{\Delta [I_2]}{\Delta t}=\frac{\Delta [H_2]}{\Delta t}=\frac{\Delta [HI]}{2\Delta t} $

C) $ \frac{\Delta [H_2]}{\Delta t}=\frac{1}{2}\frac{\Delta [I_2]}{\Delta t}=-\frac{\Delta [HI]}{\Delta t} $

D) None of these

Show Answer

Answer:

Correct Answer: A

Solution:

For the given reaction :

$ -\frac{\Delta [I_2]}{\Delta t}=-\frac{\Delta [H_2]}{\Delta t}=\frac{1}{2}\frac{\Delta [HI]}{\Delta t} $
