The temperature dependence of the rate constant for a reaction is tabulated as follows. temperature (k) k (m−1s−1) 600. 0.028 650. 0.22 700. 1.3 750. 6.0 800. 23 calculate ea and a.

See attached photos for the solution:

 k is the rate constant

 T is the absolute temperature (in kelvins)

 A is the pre-exponential factor, a constant for each chemical reaction. According to collision theory, A is the frequency of collisions in the correct orientation

 Ea is the activation energy for the reaction (in the same units as R*T)

 R is the universal gas constant.
