Question

For the elementary process, CO(g) + N2O(g) ? CO2(g) + N2(g), the rate constant increases by a factor of 108.5 when the temperature is raised from 298K to 339K.
The value of the gas constant is R = 8.314 J/mol-K.
Activation energy is 96kJ/mol
Based on their activation energies and energy changes and assuming that all collision factors are the same, which of the following reactions would be slowest in the forward direction?



a) Ea = 186; E = -61;
b) Ea = 68; E = -219;
c) Ea = 263; E = -65;
d) Ea = 312; E = 287;
e) Ea = 111; E = -183;
