# 3 questions on vapor pressure, volatility, and H-bonding

1) As the volatility of a liquid increases, its equilibrium vapor pressure?
A) increases
B) decreases
C) remains the same

2) Which substance contains molecules that will not form hydrogen bonds?
A) hydrogen
B) hydrogen fluoride
C) water
D) ammonia

3) At what temp would CO2 gas be most soluble?
A) 10 C
B) 20 C
C) 30 C
D) 40 C

#### Solution Preview

1. A more volatile liquid means it escapes into the gas phase from the liquid phase at a lower atmospheric pressure. The equilibrium vapor pressure is when the VP = atmospheric pressure (ie- the boiling point). So, as volatility increases, the eq vp decreases.

2. To form hydrogen bonds, you must have molecules with a lone pair of electrons (generally on N, O, S, or a ...
