Stoichiometry Specific gravity on API scale is given by the relation(where, G = specific gravity at 15.5°C). °API = 200(G - 1) °API = (141.5/G) - 131.5 °API = 145 - (145/G) °API = (140/G) - 130 °API = 200(G - 1) °API = (141.5/G) - 131.5 °API = 145 - (145/G) °API = (140/G) - 130 ANSWER DOWNLOAD EXAMIANS APP

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 1335 1525 1225 1735 1335 1525 1225 1735 ANSWER DOWNLOAD EXAMIANS APP
