Methyl salicylate, C8H8O3, the odorous constituent of oil of wintergreen, has a vapour pressure of 1.00 torr at 54.3oC and 10.0 torr at 95.3oC.
a) What is its vapour pressure at 25oC?
b) What is the minimum number of liters of air that must pass over a sample of the compound at 25oC to vaporize 1.0 mg of it?

1. Use the Arrhenius equation. Use p1 and p2 and T1 and T2 and solve for Ea (actgivation energy) in Joules, then plug that back into the Arrhenius equation and either p1 or p2 to calculate p at 25C.
