24. Suppose that 0.350 mol of A and 0.520 mol of B are placed a 1.50 L container and the following hypothetical equilibrium is established. If the equilibrium amount of C is 0.150 mol, what is the equilibrium constant for this reaction?
A(g) +2B(g) >3C(g)

Best ResponseYou've already chosen the best response.0First, you're going to want to set up an ICE chart: \[[A]_0=\frac{0.350mol}{1.5L}=0.23M\]\[[2B]_0=\frac{0.520mol}{1.5L}=0.35M\]\[\Delta [A]=\frac{1}{3}(0.10M)=0.033M\]\[\Delta [2B]=\frac{2}{3}(0.10M)=0.067M\] Concentration (M) [A] [2B] [3C] Initial 0.23 0.35 0 Change 0.033 0.067 0.100 Equilibrium 0.200 0.280 0.100 Then, we can go ahead and plug these in to our K_c equation:\[K_c=\frac{[C]^3}{[A][B]^2}=\frac{(0.100)^3}{(0.200)(0.280)^2}=6.38*10^{2}\]\[K_c=6.38*10^{2}\]

Best ResponseYou've already chosen the best response.0I forgot to write down a calculation which may cause confusion. I just want to clarify:\[[3C]_E=\frac{0.150mol}{1.5L}=0.100\]
