One mole methane undergoes complete combustion in a stoichiometric amount of air. the reaction proceeds as ch, + 20, → co2 + 2h2o both the reactants and the products are in gas phase. ah, = - 730 kj/mol of methane. if the average specific heat of all gases and vapours is 40 j/mol k, the maximum temperature rise of the exhaust gases in k would be approximately equal to (a) 1225 (b) 1335 (c) 1525 (d) 1735
