# equilibrium and equations involving Kc watch

1. Kc is 15.6mol^-1dm^3 at 370 degrees celcelus for the system

PCl3 (g) +Cl2 --> <--- PCl5 (g)

at equilibrium, the concentration of PCL5 is 0.6mol dm^-3

what are the concentrations of PCL3 and CL2 if there were eqimolar concentrations of each at the start? (concentration at the start and at equilibrium)

Have you been able to do anything about the question? otherwise, it seems to me that you are simply seeking someone to do your work for you.
3. I didnt understand how the temperature affected it. Thats what confused me. i know as it is a one to one ratio, the inital amounts of the reactants go down by the same amount to form the product, and that the amount that the product goes up by in a one to one ratio is what the reactants go down by.

Temperature affects the position of equilibrium. You are not expected to do anything with it, it's just there to 'set the scene'...
