1. ### Raoult's law problem

I have not learned that equation yet, is there another way to solve this problem?
2. ### Raoult's law 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?
3. ### Raoult's law problem

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*...
4. ### Thermodynamics equilibrium constant problem

Thanks for the reply! I appreciate the help! I asked my professor and I figured it out.
5. ### Thermodynamics equilibrium constant problem

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?
6. ### Thermodynamics equilibrium constant problem

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.
7. ### Thermodynamics equilibrium constant problem

They did not say what the initial pressures are.
8. ### Thermodynamics equilibrium constant problem

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...
9. ### Chemistry Thermodynamics mole ratio question

2, I think I get it now, thanks!
10. ### Chemistry Thermodynamics mole ratio question

Homework Statement A sample of K (s) of mass 2.740g undergoes combustion in a constant volume calorimeter at 298.15K . The calorimeter constant is 1849 J/K , and the measured temperature rise in the inner water bath containing 1450 of water is 1.60K Calculate the internal energy of formation...
11. ### Electric Field diagram question

http://imgur.com/a/Hg23p 1. Homework Statement In each of the figures below some electric field lines are drawn. But in most cases, there are mistakes. For each drawing, select which of the above rules are broken or if the diagram is essentially correct. http://imgur.com/a/Hg23p Homework...
