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 Significantly less than 4.69 atm Nearly equal to 4.69 atm Significantly more than 4.69 atm Indeterminate due to lack of data Significantly less than 4.69 atm Nearly equal to 4.69 atm Significantly more than 4.69 atm Indeterminate due to lack of data ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry A rigid vessel containing three moles of nitrogen gas at 30°C is heated to 250°C. Assume the average capacities of nitrogen to be Cp = 29.1 J/mole.°C and, Cv = 20.8 J/mole.°C. The heat required, neglecting the heat capacity of the vessel, is 4576 J 13728 J 19206 J 12712 J 4576 J 13728 J 19206 J 12712 J ANSWER DOWNLOAD EXAMIANS APP
