Stoichiometry One kg of saturated steam at 100°C and 1.01325 bar is contained in a rigid walled vessel. It lias a volume of 1.673 m³. It cools to 98°C ; the saturation pressure is 0.943 bar ; one kg of water vapour under these conditions has a volume of 1.789 m³. The latent heat of condensation (kJ/kg⁻¹ ) under these conditions is 540 2676 40732 2263 540 2676 40732 2263 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
