The rate constant, the activation energy and the Arrhenius parameter of a chemical reaction at 25°C are 3.0 × 1 0 - 4 s - , 104.4 kJ m o l - 1 and 6 × 1 0 14 s - 1 respectively. The value of the rate constant as T → ∞ is
Options
- A2.0 × 1 0 18 s - 1
- B6.0 × 1 0 14 s - 1
- Cinfinity
- D3.6 × 1 0 30 s - 1
Correct answer
B. 6.0 × 1 0 14 s - 1
Step-by-step solution
k = A e - E a / R T (Arrhenius equation) when T → ∞ k = A e 0 , or k = A Thus k = 6 × 1 0 14 s - 1
