Butyric Acid


Evaporation rate is directly related to the vapor pressure of a compound. The higher the vapor pressure, the faster it will evaporate. Temperature also affects the evaporation rate, so the comparison of vapor pressures must be at the same temperature.

Thus, the compound with the lowest vapor pressure will take the longest to evaporate.
