I have not learned that equation yet, is there another way to solve this problem?

The initial total pressure is 4 atm. Should I just find the final total pressure first using the clasius clapeyron equation? The problem is if I use the CC equation, which enthalpy of vaporization should I use?

Homework Statement Consider air to be made up of only N2 (78 mole %), O2 (21%) and Ar (1%) Estimate the mole fractions of each in both the liquid and gas phases if 1 mole of air at 300 K and 4 atm. total pressure were cooled to 65 K in the same volume Homework Equations Raoult's law Pi = Pi*...

Thanks for the reply! I appreciate the help! I asked my professor and I figured it out.

Oh right, just had a brain fart, don't know how I missed that. So how should I proceed? Should I set up an equation for Keq?

So assuming that there is no product in at the beginning of the reaction, partial pressure of N2 would be 1/3 bar and the partial pressure of H2 would be 2/3 bar.

They did not say what the initial pressures are.

Homework Statement N2 + 3H2 --> 2NH3 (all gases) Why is such a high pressure needed? Calculate the equilibrium constant at 500k then estimate the percentage conversion at equilibrium at 1 bar total pressure, assuming the stoichiometric ratio of N2:H2 is 1:3. Repeat the process at 50 bar...

2, I think I get it now, thanks!
