Question

The activation energy EA for particular reaction is 37.8 Kj/mol. If the rate constant at 280 K is 0.178 M/s, then what is the value of the rate constant at 381 K?

Answer 1

The value of the rate constant at 381 K is:

k2 = k1 * (k2/k1) = 0.178 M/s * 4.50 = 0.801 M/s (rounded to three significant figures)
