Solution: A series of experiments were performed to determine the rate constant for the reaction  2H2S(g) + 3O2(g) → 2H2O(g) + 2SO2(g) at different temperatures. A plot of ln k against 1/T was a straight line

Problem

A series of experiments were performed to determine the rate constant for the reaction 

2H2S(g) + 3O2(g) → 2H2O(g) + 2SO2(g)

at different temperatures. A plot of ln k against 1/T was a straight line with a slope of −1.5275x104 and intercept of 23.6. What is the frequency factor?

a) 196.2

b) 23.6

c) 1.5275x104

d) 5.63x10−11

e) 1.78x1010
