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. Mole fraction of water vapour in the product gases is about 0.40 0.67 0.33 0.19 0.40 0.67 0.33 0.19 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Gases diffuse faster compared to liquids because of the reason that the liquid molecules Are held together by stronger inter-molecular forces Move faster Have no definite shape Are heavier Are held together by stronger inter-molecular forces Move faster Have no definite shape Are heavier ANSWER DOWNLOAD EXAMIANS APP
