1. The following data were obtained for the reaction

2 ICl (g) + H₂ (g) → I₂ (g) + 2 HCl (g) 

 

Experiment	[ICl]0  (M)	[H2]0 (M)	Initial Rate (M/s)
1	0.0015	0.0015	3.7 x 10-7
2	0.0030	0.0015	7.4 x 10-7
3	0.0030	0.0045	2.2 x 10-6

 

a) What is the initial rate of change of [ICl] in experiment 1?

b) What is the rate law for this reaction?

c) What is the overall order of this reaction?

d) What is the rate constant for this reaction? Don’t forget units!

e) Does this reaction happen in a single elementary step? Explain your reasoning in 1-2 sentences.
