NEET Chemistry Rate of Reaction MCQ Question
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?
0.1 mol/L/s
0.2 mol/L/s
0.4 mol/L/s
0.05 mol/L/s
Correct Answer
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.
