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.
