NEET Chemistry Rate of Reaction MCQ Question

Type: MCQ-numerical-Easy-Class 12

For the reaction H2(g) + I2(g) → 2HI(g), if the rate of formation of HI is 0.2 mol/L/s, what is the rate of disappearance of H2?

A

0.1 mol/L/s

B

0.2 mol/L/s

C

0.4 mol/L/s

D

0.05 mol/L/s

Correct Answer

Option A

Detailed Explanation

The rate of disappearance of H2 is half the rate of formation of HI because the stoichiometric coefficient of HI is twice that of H2. Thus, the rate is 0.2/2 = 0.1 mol/L/s.
