A 0.831-g sample of SO3 is placed in a 1.00 L container and heated to 1100 K. The SO3 decomposes to SO2 and O2: 2SO3 (g) <---> 2SO2 (g) + O2 (g). At equilibrium the total pressure in the container is 1.300 atm.
1. Find the value of Kp for this reaction at 1100 K.
2. Find the value of Kc for this reaction at 1100 K.
