Homework Help: Chemistry(Please help)

Posted by Hannah on Wednesday, March 14, 2012 at 10:00pm.

For the reaction, 2 SO2(g) + O2(g) == 2 SO3(g), at 450.0 K (Kelvin) the equilibrium constant, Kc, has a value of 4.62. A system was charged to give these initial concentrations, (SO3) = 0.254 M and (O2) = 0.00855 M, and (SO2) = 0.500 M. In which direction will it go?

I think I posted this once before but I do not remember what the respond was. Am I suppose to plug the values into the Kc equation?

4.62 = (0.245)^2 / (0.500)^2 (0.00855)
