Question

1. For the equilibrium system shown below,Kc= 1.4 x 10^-4. If the concentration of A is 0.24 mol/L, what is the concentration of D? 3 A(g) + B(s) ⇔ C(s) + 2 D(g)

2. A student placed the same chemical amount of SO_2(g) and NO_2(g) into a 1.0 L container. At equilibrium, the concentration of both SO_3(g) and NO_(g) was 0.30 mol/L.

What was the initial concentration of the SO_2(g) and NO_2(g)  ?

SO_2(g) + NO_2(g) ⇔ SO_3(g) + NO_2(g)    Kc= 9.5
