Answers:
Option B
Option A.
Explanation:
For part A
The applicable equation is the Clausius-Clapeyron equation. The equation relates the vapor pressure and temperature like this:
We know that P₁ = 6.63 torr
R = 8.314 kj/mol
T₁ = 106.5⁰ = 379.65 K
T₂ = 38⁰ = 311.15 K
ΔH = 43 300J/mol
using the equation to solve for P₂, we get 67.8 torr
For part B
Water is a polar molecule. The bonds in the water are hydrogen bonds; water forms strong hydrogen bonds between the molecules. However, the gases in the air are non polar. Nitrogen and argon are inert gases - nonreactive. Nitrogen has a triple bond N≡N and argon is inert. Oxygen is a bi-atomic gas, O₂.
Hence the only forces in the water with the gases are dipole-induced dipole forces.
