| Prophet 9 FTW  | Equilibrium Constant Question You can hide this advertisement by registering. For the reaction x ⇌ Y, an initial concentration of 1.0 mol/L X is allowed to come to equilibrium. If K = 10, what is the equilibrium concentration of Y?

Today, 8:28 PM  | Re: Equilibrium Constant Question Quote:
Assuming the reaction vessel is 1 L, at anytime, there can only be 1.0 mol of reactants, i.e [x] + [y] = 1.0 x = 1.0 - [y] At equilibrium, k = 10 therefore 10 = [y]/[x] [y] = 10(1 - [y]) 11[y] = 10 [y] = 0.91 mol/L
