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.
