Type: MCQ-conceptual-Medium-Class 12
For a reaction of order n, the unit of the rate constant is:
A
mol¹⁻ⁿ Lⁿ⁻¹ s⁻¹
B
mol¹⁻ⁿ L¹⁻ⁿ s⁻¹
C
mol¹⁻ⁿ L¹⁻ⁿ s
D
mol¹⁻ⁿ L²ⁿ s⁻¹
Correct Answer
Option A
Detailed Explanation
For nth order reaction, Rate = k[A]ⁿ. The unit of k is derived from the rate equation, resulting in mol¹⁻ⁿ Lⁿ⁻¹ s⁻¹.
