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 Indeterminate due to lack of data Significantly more than 4.69 atm Significantly less than 4.69 atm Nearly equal to 4.69 atm Indeterminate due to lack of data Significantly more than 4.69 atm Significantly less than 4.69 atm ANSWER DOWNLOAD EXAMIANS APP
