2P(s) + 3Cl2(g) -> 4PCl3(l) at 298K
Estimate the boiling point of PCl3. What approximation are you making when calculating the boiling point?
If the vapor pressure of PCl3 gas above the liquid were 0.085atm at 30 degrees Celsius, would you expect the reaction to proceeds towards more evaporation or would you expect condensation of gas into liquid?
