Chemical Reaction Engineering
At a given value of E/R (ratio of activation energy and gas constant), the ratio of the rate constants at 500°K and 400°K is 2, if Arrhenious law is used. What will be this ratio, if transition state theory is used with the same value of E/R?

1.6
2
2.24
2.5

Chemical Reaction Engineering
For a heterogenous catalytic reaction, A + B → C, with equimole feed of A and B, the initial rate - rA0 is invariant with total pressure. The rate controlling step is

Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase
Surface reaction between A in the gas phase and absorbed B
Surface reaction between absorbed A and absorbed B
Desorption of C
