Question

The decomposition of formic acid on gold surface follows first order kinetics. If the rate constant at 300 K is 1.0 × 10 s and the activation energy E = 11.488 kJ mol , the rate constant at 200 K is ______ × 10 s . (Round off to the Nearest Integer). (Given: R = 8.314 J mol K ) -3 -1 a -1 -5 -1 -1 -1
