At 791K and relatively low pressures, the gas-
phase decomposition of acetaldehyde
(CH3CHO) is second order in acetaldehyde.
CH3CHO(g) CH4(g) + CO(g)
The total pressure of a particular reaction
mixture was found to vary as follows:
Time (s) 0 75 148 308 605 Total pressure (atm)
0.500 0.583 0.641 0.724 0.808
(a) Use the pressure data to determine the value
of the rate constant in units of atm-1s-1. (b)
What is the rate constant in the usual units of
M-1s-1? (c) if the volume of the reaction
mbdure is 1.00 L, what is the total amount of
heat liberated (in joules) after a reaction time of
605 s?
