A reaction has a rate constant of 0.000122s-1 at27oC and 0.228s-1 at 77oC. a)Determine the activation energy of the reaction. b)What is the value of the rate constant at17oC

a)

b)

Explanation:

Hello,

a) In this case, for this kinetics problem, we can consider the temperature-dependent Arrhenius equation:

In such a way, for the given temperatures and rate constant, we compute the activation energy as follows:

b) In this case, we use the previously computed activation energy in order to compute the rate constant at the asked 17°C:

Best regards.
