6. Solving a chemistry problem

1. The reaction C O2 = CO2 proceeds on the inner surface of the coal channel, through which air is passed. The effective rate constant changes with temperature as shown below:
T, K 773 873 973 1073 1173 1273 1373
K* 0.073 0.447 2.15 6.81 13.72 19.49 23.4
Using graphic constructions, determine in what temperature range the reaction proceeds in the kinetic mode, and find its activation energy.
