Question

Half-life of reaction is inversely proportional to the square of initial concentration. The order of reaction is

• A. 0
• B. 1
• C. 2
• D. 3

Answer 1

Answer: (D)

We have $t_{1/2}\propto \frac{1}{a^{n-1}}$ When $n=3$ $t_{1/2}=\frac{1}{a^3-1}=\frac{1}{a^2}$ $\therefore$ Order of reaction = 3
