The rate of a reaction quadruples when temperature changes from 27^ C to 57^ C . Calculate the energy o activation. Given R =8.314 ~J ~K ⁻¹ ~mol ⁻¹, 4=0.6021

Options

  1. A380.4 ~kJ / mol
  2. B3.80 ~kJ / mol
  3. C3804 ~kJ / mol
  4. D38.04 ~kJ / mol

Correct answer

D. 38.04 ~kJ / mol

Step-by-step solution

aligned & ( k ₂ k ₁ )= E _ a 2.303 R ( 1 ~T ₁ - 1 ~T ₂ ) & ( 4 1 )= E _ a 2.303 R ( 1 300 - 1 330 ) & E _ a = ( (4)) 2.303 8.314 300 330 30 & =3.804 10^4 ~J / mol & =38.04 ~kJ / mol aligned
