The first order rate constant for reaction of a particular organic compounded with water varies with temperature as follows:
Temperature (K) Rate Constant (s-1)
300................................3.2 × 10-11
320................................1.0 × 10-9
340................................3.0 × 10-8
355................................2.4 × 10-7
From these data, calculate the activation energy in units of kJ/mol.
