Problem
For an elementary gas-phase reaction, the fraction of collisions with sufficient energy is 2.0 % at 298 K and 3.6 % at 308 K. All other factors (collision frequency and orientation probability) remain unchanged.
By what factor does the initial reaction rate at 308 K exceed that at 298 K?
(a) 2.0
(b) 3.6
(c) 1.8
(d) 1.6
