Question

A certain reaction rate increases \(1000\) folds in the presence of a catalyst at \(27^\circ\mathrm{C}\). The activation energy of the original pathway is \(98\mathrm{\ kJ/mol}\). What is the activation energy of the new pathway?

• A. \(80.77\mathrm{\ kJ}\)
• B. \(56.38\mathrm{\ kJ}\)
• C. \(24.67\mathrm{\ kJ}\)
• D. \(90.43\mathrm{\ kJ}\)

Hint:

Use Arrhenius equation: \(\ln(k_2/k_1) = (E_{a1} - E_{a2})/RT\).

Answer 1

The Correct Option is A
