How much faster would a reaction proceed at 25^ C than at 0^ C if the activation energy is 65 ~kJ ?

Options

  1. A4 times
  2. B6 times
  3. C12 times
  4. D11 times

Correct answer

D. 11 times

Step-by-step solution

We known, aligned 2.303 k₂ k₁ & = E_a R [ T₂-T₁ T₁ T₂ ] .2 .303 k₂ k₁ & = 65 10^3 8.314 [ 25 298 273 ] k₂ k & =11.5 . aligned The reaction would proceed 11 times faster.
