Reposting with correct information..Carbon tetrachloride (CCl4) and benzene (C6H6) form ideal solutions.  Consider an equimolar solution of CCl4 and C6H6 at 25°C.  The vapor above this solutionis collected and condensed.  Using the following data, determine the composition in mole fraction of the condensed vapor.

Substance		∆Gf°    
C6H6 (l)           124.50 kJ/mol
C6H6 (g)		129.66 kJ/mol
CCl4 (l)		-65.21 kJ/mol
CCl4 (g)		-60.59 kJ/mol

Delta G = -RTLNK
For c6h6 (l) to c6h6 (g) equilibrium, delta G = 129.66-124.50 = 5.16 kJ/Mol
Plug this value into the equation above and solve for the value of K, which is simply the ratio of product to reactant.

Repeat this calculation for ccl4.
