A first-order decomposition reaction of compound A was monitored at two temperatures. The experimentally determined rate constants are listed below.
Temperature (K)
k (s⁻¹)
298
1.2×10−3
318
5.4×10−3
Use the data to address the following.
(a) Determine the activation energy for the decomposition of A. Clearly show the steps of your calculation.
(b) Predict the numerical value of the rate constant at 308 K, assuming the same kinetic model applies. Show reasoning.
