1. The problem statement, all variables and given/known data Compound A can react to form B and C according to the following A<->2B Kc=1 A<->C Kc=1 If 1 mole of A is solved into 1 litre of water, what will the concentration of A be after equilibrium has been reached? 2. Relevant equations ICE-tables(?) A<->2B+C Kc=(^2[C])/[A] 3. The attempt at a solution Doing this homework the usual way, doing the ICE tables, I ended up with the solution c(A)=0.39, which is not correct according to the answer. This made me think that perhaps this can't be solved assuming that A<->2B+C , Kc=1, C(A) at start=1, but instead there is some other method? I would be grateful to have some tips on how I should approach this problem.
