Question

How do you answer c,d, the other d 1. Consider the following reaction, CH4(g) + 4 NO(g) 2 N2(g) + CO2(g) + 2 H2O(g) and write a proper equation relating the rates for each of a and b: a. The rate of formation of N2 to the rate of formation of CO2. b-The rate of formation of CO2 to the rate of consumption of NO. c. What is the rate of formation in [H2O], if the rate of disappearance of NO is -2.2 x 10 M/s? d. What is the rate of disappearance of CHe, if the of appearance of CO2 is 4.5 x 10 M/s? d. What is the overall rate of this reaction using the rate of appearance of CO2 is 4.5 x 105 Ms?

Explanation / Answer

1. from equation :

rate of reaction = -d[CH4]/dt = -1/4d[NO]/dt = +1/2d[N2]/dt = +d[CO2]/dt = +1/2d[H20]/dt

from the relation,

a) rate of formation of N2 = +d[N2]/dt = +2d[CO2]/dt

b) rate of formation of CO2 = +d[CO2]/dt = -1/4d[NO]/dt

C) rate of formation of H2O = d[H20]/dt = 1/2d[NO]/dt

                            = -1/2*(-2.2*10^-4)

                            = 1.1*10^-4 M/s

d) rate of disappearance of CH4 = -d[CH4]/dt = +d[CO2]/dt = -4.5*10^-5 M/s

e) over all rate of reaction = +d[CO2]/dt = 4.5*10^-5 M/s
