For the equilibrium CH3COOCH3(aq) + H2O ? CH3COOH + CH3OH Kc = 3.00 @ 298K If a solution initially contains 0.15 M acetic acid and 0.15 methanol calculate the equilibrium concentrations of ethyl acetate, acetic acid and methanol at this temperature. I dont know what im doing wrong im setting up an ICE table CH3COOCH3(aq) + H2O ? CH3COOH + CH3OH 0 0 0.15 0.15 -x +x +x i get .0225 + 0.30x+x^2 = 3.00 but i get both negative when i do the quadratic
