Question
The following kinetic data were collected at 1200 K. a. What is the rate-law expression for the reaction? Rate = b. What is the value of the rate constant at 1200 K? Number Reducing NO Emissions 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. The following kinetic data were collected at 1200 K. a. What is the rate-law expression for the reaction? Rate =Explanation / Answer
a) rate = k [NH2]^x[NO]^y
from data
012= k [1x10^-5]^x[1x10^-5]^y-----------------(1)
0.24= k [2x10^-5]^x[1x10^-5]^y-------------(2)
0.36= k [2x10^-5]^x[1.5x10^-5]^y----------------(3)
by solving 1 and 2 we get x=1
by solving 2 and 3 we get y=1
now
rate = k [NH2]^x[NO]^y
rate = k [NH2]1[NO]1
b) 012= k [1x10^-5]^1[1x10^-5]^1
k= 12x108 M-1s-1
