Stoichiometry At 100°C, water and methylcyclohexane both have vapour pressures of 1 atm. Also at 100°C, the latent heats of vaporisation of these compounds are 40.63 kJ/mole for water and 31.55 kJ/mole for methylcyclohexane. The vapour pressure of water at 150°C is 4.69 atm. At 150°C, the vapour pressure of methylcyclohexane would be expected to be Nearly equal to 4.69 atm Significantly less than 4.69 atm Indeterminate due to lack of data Significantly more than 4.69 atm Nearly equal to 4.69 atm Significantly less than 4.69 atm Indeterminate due to lack of data Significantly more than 4.69 atm 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 1225 1525 1735 1335 1225 1525 1735 1335 ANSWER DOWNLOAD EXAMIANS APP
