The decomposition of acetaldehyde (X) to methane and carbon monoxide follows four-step free radical mechanism. The overall rate of decomposition of X is
denote the rate constants of the elementary steps, with corresponding activation energies (in kJ mol-1) of 320, 40, and 0, respectively. The temperature dependency of the rate constants is described by Arrhenius equation. CX denotes the concentration of acetaldehyde. The rate constant for the overall reaction is koverall. The activation energy for the overall reaction (in kJ mol-1) is _______ (round off to nearest integer).
