STANDARD Chemistry Rate of Reaction MCQ Question

Type: MCQ-numerical-Medium-Class 12

In a reaction, 2X → Y, the concentration of X decreases from 3.0 moles/litre to 2.0 moles/litre in 5 minutes. The rate of reaction is:

A

0.1 mol L⁻¹ min⁻¹

B

5 mol L⁻¹ min⁻¹

C

1 mol L⁻¹ min⁻¹

D

0.5 mol L⁻¹ min⁻¹

Correct Answer

Option A

Detailed Explanation

The rate of reaction is calculated as the change in concentration of X over time. The change is 1.0 mol L⁻¹ over 5 minutes, giving a rate of 0.1 mol L⁻¹ min⁻¹.
