Question

For a reaction E_a = 0 and k = 3.2 × 10⁴ s^–1 at 300 K. The value of k at 310 K would be :

• A. 6.4 × 10⁴ s^–1
• B. 3.2 × 10⁴ s^–1
• C. 3.2 × 10⁸ s^–1
• D. 3.2 × 10⁵ s^–1

Answer 1

Answer: (B)

3.2 × 10⁴ s^–1

Answer 2

k = $Ae^{- E_{a}/RT}$

When E_a = 0, k = A = constant

\ k₃₁₀ = k₃₀₀ = 3.2 × 10⁴ s^–1
