Question 2
What is Kc for the following equilibrium when the equilibrium concentration of each substance is: [SO2]= 0.60 M, [O2] = 0.82 M and [SO3] = 1.90 M ?
2SO2(g) + O2(g) ↔ 2SO3(g)
The equilibrium constant (Kc) for the give reaction is:
Kc = [SO3]2 / [SO2]2 [O2]
= (1.90)2 M2 / (0.60)2 (0.8321) M3
= 12.239 M-1 Approx.
Hence, Kc for the equilibrium is 12.239 M-1
