A certain reaction rate increases 1000 folds in the presence of a catalyst at 27^ C . The activation energy of the original pathway is 98 ~kJ / mol . What is the activation energy of the new pathway?

Options

  1. A80.77 kJ
  2. B56.38 kJ
  3. C24.67 kJ
  4. D90.43 kJ

Correct answer

A. 80.77 kJ

Step-by-step solution

k₂ k₁ = 1000 aligned = & E₁-E₂ R T & = 98000-E₂ 8.314 300 E₂ & (catalyst) =80.77 ~kJ aligned
