In this reaction: SO2(g) S2O4(g),

1. Calculate the Kp and Kc of the above reaction if, at equilibrium, there are 0.02 moles of S2O4 and 0.90 moles of SO2 at 75 oC inside a 20.00L container.

2. Using the Kp in (1), calculate the new equilibrium pressures (in atm) if the volume of the container is increased to 50.00L at the same temperature.

3. From that in (1), calculate the new equilibrium pressures if an additional 0.50 moles of SO2 gas is added in the mixture at the same volume and temperature.
