Given the following balanced equation, determine the rate of reaction with respect to [N2]. N2(g) + 3 H2(g) → 2 NH3(g)

A reaction is found to have an activation energy of 22.5 kJ/mol. If the rate constant for this reaction is [x] M -1s -1 at [y] K, what is the rate constant at [z] K?  Report your answer with three significant figures and the correct units.  To use scientific/exponential notation to represent numeric values. Eg., -0.0001 can be written as 1.0e-4 or as 1.0E-4. Spaces are not allowed.
