consider the reaction:
CO(aq) + Cl2 (aq) --> COCl2 (aq).
Calculate Delta G at non standard conditions. T = 298.15K. Concentration of COCl2 is reduced to 0.01832 M while the concentrations of CO and Cl2 remain 1M. Delta G rxn = -67.4 kj.

Even the correct formula to use would be a HUGE help!
Hey Tara,
Hmm, I'm not too sure about this question, but I'd guess it has something to do with the following formula:
G = G(not)+ RTlnQ
So basically G(not) = -67.4 kJ
R= 0.008314 kJ mol^-1 K^-1.(molar gas constant)(Note that units must be kJ to match up with the G(not) which is in kJ.)
Then.. T = 298.15K as you are given.
Then we need to calculate Q.
Being the reaction quotient, it is obtained by (concentration COCl2)/[(concentration CO)(concentration Cl2)] [In short, concentration of products/reactants]
You should get Q = (0.01832)/[(1)(1)]
Then just apply the formula.
If I'm not wrong, you should get -74.6kJmol^-1. :)
