Question

The rate constant of a first order reaction is 10^–3 min^–1 at 300 K. The temperature coefficient of the reaction is 2. What is the rate constant of the reaction at 350 K approximately ?

• A. 16 × 10^–3
• B. 64 × 10^–3
• C. 32 × 10^–3
• D. 2⁵⁰

Answer 1

Answer: (C)

32 × 10^–3

Answer 2

$\frac{k_{T_{2}}}{k_{T_{1}}}$= (µ)^DT/10

or $\frac{k_{T_{2}}}{10^{- 3}}$ = 2⁵

or $k_{T_{2}}$ = 2⁵ × 10^–3 = 32 × 10^–3
