how can you solve an equilibria problem when you dont know the initial values, and the only thing you know is the value for Kc and the value for the reactants....can someone please help i am stuck!!

what values of the reactants do you have?

can you perform a material balance?

please provide the chemical equation.

it is my previous question on equilibria that i dont understand, i know that am doing something wrong, and second i dont know what to do to solve for x

i think the table is wrong too, because 1.2mol was not the initial value but the value at equilibrium....

If the concentrations of the any reactants aren't given, you have to assume they are 0.
Second, to solve for x, you make what is called an ICE diagram, which stands for Initial-Change-Equilibrium.
If you give the initial amount given and possibly a balanced equation it would be easier to help you  :P
