1. Nitric oxide gas reacts with chlorine gas according to the equation

2 NO(g) + Cl₂(g) ® 2 NOCl(g)

The following initial rates of reaction have been observed for certain reactant concentrations:

a. What is the rate law describing this reaction?

b. What is the overall rate order?

c. Determine k.

<?xml:namespace prefix = o ns = \"urn:schemas-microsoft-com:office:office\" />

Type your question here

rate=k[cl2]^a[no]^b

dividing trial 1,2

[2]^a=4

=>a=2

dividing1,3

[3]^2[2]^b=8

=>b=1

total order 3

substituting in trail 1

1.14=k[0.5]^2[0.5]

k=9.12
