The simplified mechanism shown below is for the thermal decomposition of ethanal: CH3CHO – k → •CH3 -СНО CH3 + CH3CHO – k2→ CH4 CH3CO. + CH3CO- - k3 → CO + •CH3 CH3 •CH3 - k4 → + C2H6 - (i) Draw the molecular structure of ethanal. (ii) Identify each of the reaction steps in the mechanism. (iii) Explain why this is a linear chain and not a branched chain reaction. (iv) Identify the reactive intermediates (chain carriers). (v) Derive the rate law for the formation of CO which is consistent with the following experimental rate law: d[CO]/dt = kexp[CH3CHO]2 What additional experimental evidence could be obtained to support this proposed mechanism? (vi) (vii) What are the units of kexpt?
