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________?
ASignificantly more than 4.69 atm
BSignificantly less than 4.69 atm
CNearly equal to 4.69 atm
DIndeterminate due to lack of data
Correct answer
A. Significantly more than 4.69 atm
Explanation
The correct answer is Significantly more than 4.69 atm.
