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. [Wrong Answer] |
B. | nearly equal to 4.69 atm. [Wrong Answer] |
C. | significantly more than 4.69 atm. [Correct Answer] |
D. | indeterminate due to lack of data [Wrong Answer] |
