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_________________?
(A) Significantly less than 4.69 atm
(B) Nearly equal to 4.69 atm
(C) Significantly more than 4.69 atm
(D) Indeterminate due to lack of data
