Answer to Question #184193 in General Chemistry for Natalia Pocica

Question

The reaction between NO and Cl₂ is represented by the following reaction:

2 NO _(g) + Cl_2 (g) → 2 NOCl _(g) 

The data below were obtained:

[NO] 0.250 M, 0.500 M , 0.250 M,

[Cl₂] 0.250 M, 0.250 M, 0.500 M

Rate 1.43 x 10^-6 M/s , 5.72 x 10^-6 M/s , 2.86 x 10^-6 M/s

Assume that the rate law is in the following form: 

Rate = k[NO]^a[Cl₂]^b

Part A

Determine the value of “a”.

Part B

Determine the value of “b”.

Part C

Calculate “k”.

Part D

Calculate the rate of reaction when the concentration of NO is 0.345 M and the concentration of Cl₂ is 1.23 M.
