The rate constant of a first order reaction at 27^ C is 10⁻³ ~min ⁻¹ . The temperature coefficient of this reaction is 2 . What is the rate constant (in min ⁻¹ ) at 17^ C for this reaction?
Options
- A10⁻³
- B5 10⁻⁴
- C2 10⁻³
- D10⁻²
Correct answer
B. 5 10⁻⁴
Step-by-step solution
Temperature coefficient, = k_t+10 k_t 2= 10⁻³ k_t k_t= 10⁻³ 2 = 10 10⁻⁴ 2 =5 10⁻⁴
