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 1225 1335 1525 1735 1225 1335 1525 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry According to Raoult's law, "The vapor pressure exerted by component in a solution is proportional to the mole fraction of that component." Raoult's law is not applicable under the following assumption/condition. The attractive forces between like and unlike molecules are almost equal The component molecules are non polar and are of almost equal size In the formation of solution, chemical combination/molecular association between unlike molecules takes place No component is concentrated at the surface of the solution The attractive forces between like and unlike molecules are almost equal The component molecules are non polar and are of almost equal size In the formation of solution, chemical combination/molecular association between unlike molecules takes place No component is concentrated at the surface of the solution ANSWER DOWNLOAD EXAMIANS APP

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