The simple Rice-Herzfeld mechanism for decomposition of asethaldehyde is:

          CH3COOH    -.> CH3 + CHO

                   CHO     -> CO   + H

   H   + CH3CHO -> H2 + CH3CO

CH3 + CH3CHO -> CH4 + CH3CO


                CH3CO -> CH3 + CO

                   2CH3    -> C2H6

If the rate of the first stage is ignored, then the decomposition rate of asethaldehyde follows a 3/2 order. Look for effective rate constants.
