Video Solution

For the elementary step, A ➞ Products, specific rate constants at two different temperatures were measured.

k (s-1)	T (˚C)
5.0	200.
10.0	400.

What is the activation energy (in kJ/mol) for this elementary step?

Video Solution

For the elementary step, 2 X ➞ Products, the specific rate constant at 400. ˚C is 17. M^-1s^-1. If the activation energy for this elementary step is 37 kJ/mol, what is the specific rate constant at 100. ˚C?
