The thermal decomposition of acetaldehyde (CH3CHO) is thought to follow the Rice-Herzfeld mechanism shown below:
CH3CHO--k1--->CH3 + CHO
CH3 + CH3CHO --k2-->CH4 + CH2CHO
CH2CHO--k3-->CO + CH3
CH3 + CH3--k4-->C2H6
Apply the steady state approximation to determine expressions for the rate of production of methane, CH4, and of ethane, C2H6.
