Question:

For the reaction 2A₂(g) + ¼X(g) → 2A₂X(g),If the volume is increased to double its value by decreasing the pressure on it. If the reaction is first order with respect to X and second order with respect to A₂, the rate of reaction will:

Decrease by eight times of its value
Increase by eight times of its value
Increase by four times of its value
Remain unchanged

Verified By Collegedunia

The Correct Option is A

Solution and Explanation

When the volume is doubled, the concentration of gases will halve, meaning that both [A$_2$] and [X] will be halved, and the rate decreases by eight times.
