A reaction is prepared by adding 2.000 mol each of H2, 12, and HI gases to a 1.0 L container. They are allowed to come to equilibrium, following the reaction: H2 (g) + I2(9) = 2HI(g) At the steady-state, 0.743 mol of HI remained in the container. What is the equilibrium constant Kc for this reaction under these conditions?

For the reaction 2 SO2 (g) + O2(g) = 2 SO3 (g) in a sealed glass vessel with temperature held constant, the initial gas mixture contains 0.537 M SO2, 0.566 M 02, and no SO3. At equilibrium, it was found that 0.139 M SO3 had been produced. Calculate the equilibrium constant for this reaction. You can do this by following these steps: Determine the equilibrium concentration of each reactant (as you did in the previous problems). Use these values to calculate K.
