The Rice-Herzfeld mechanism for the thermal decomposition of acetaldehyde (CH3CO) is the following below (10 points)
(1) CH3CHO ---> CH3. + CHO.
(2) CH3. + CH3CHO ---> CH4 + CH2CHO.
(3) CH2CHO. --->CO + CH3.
(4) CH3. + CH3. --->C2H6
The overall reaction is CH3CHO ---> CH4 + CO + C2H (small traces of ethane) Determine the rate law for each step if that step was the rate-determining step.
