The pyrolysis of acetaldehyde is believed to occur according to the following reaction\ sequence. Assume that all stoichiometric numbers equal 1.\ a) Derive the rate expression for the rate of disappearance of acetaldehyde, -r AC ,\ clearly stating any necessary reasonable assumptions along the way.\ b) Under what conditions would your rate expression r AC reduce to\ c) Write a set of differential equations for the concentrations of AC, C 2 H 6 , CH 4 and\ CO based on your rate expression in part A, assuming that the reaction is occurring\ in an isothermal batch reactor in the gas phase at constant volume
