Adding NH3 to the stack gases at an electric power generating plant can reduce NOx emissions. This selective noncatalytic reduction (SNR) process depends on the reaction between NH2 (an odd-electron compound) and NO.

NH2 + NO --> N2 + H2O

The following kinetic data were collected at 1200 K.

Experiment

[NH2] (M)

[NO] (M)

Rate (M/s)

1

1.00x10-5

1.00x10-5

0.12

2

2.00x10-5

1.00x10-5

0.24

3

2.00x10-5

1.50x10-5

0.36

4

2.50x10-5

1.50x10-5

0.45

 

A. What is the rate-law expression for the reaction?

B. What is the value of the rate constant at 1200 K?
