Stoichiometry One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH₄ + 2O₂ → CO₂ + 2H₂O. Both the reactants and products are in gas phase. ΔH°298 = - 730 kJ/mole of methane. If the average specific heat of all the gases/vapour is 40 J/mole.K, the maximum temperature rise of the exhaust gases in °C would be approximately equal to 1735 1335 1225 1525 1735 1335 1225 1525 ANSWER DOWNLOAD EXAMIANS APP

Stoichiometry One of the specific gravity scales is "Brix" (used speicifically for sugar solution). It is defined as Brix = 145 - (145/G) Brix = (400/G) - 400 Brix = 200 (G-1) None of these Brix = 145 - (145/G) Brix = (400/G) - 400 Brix = 200 (G-1) None of these ANSWER DOWNLOAD EXAMIANS APP
