Answer to Question #172093 in General Chemistry for Marie

Question

2NO(g)+Cl2​(g)→2NOCl(g)

Experiment [NO] (M) [Cl2] (M) Rate (M/s)

1 0.0300 0.0100 3.4 x 10^-4

2 0.0150 0.0100 3.5 x 10^-5

3 0.0150 0.0400 3.4 x 10^-4

Determine the rate law and calculate the rate constant and determine the order of the reaction with respect to Cl2.

Answer 1

From the given experimental data

Rate law,[ Rate = k[Cl][NO]² ]

Rate constant = 3.4×10^-5/(0.010)(0.03)²

=[3.8] M^-2s^-1

Order with respect to Cl2 = [1]
