Question

Part A

A certain reaction has an activation energy of 69.0 kJ/mol and a frequency factor of A1 = 5.60×10¹² M−1s−1 . What is the rate constant, k, of this reaction at 23.0 ∘C ?

Express your answer with the appropriate units. Indicate the multiplication of units explicitly either with a multiplication dot (asterisk) or a dash.

Part B

An unknown reaction was observed, and the following data were collected:

T (K)	k (M−1⋠s−1)
352	109
426	185

Determine the activation energy for this reaction.

Express your answer with the appropriate units.
