Consider the following reaction:
CO(g)+H2O(g)⇌CO2(g)+H2(g)
Kp=0.0611 at 2000 K
A reaction mixture initially contains a CO partial pressure of 1332 torr and a H2O partial pressure of 1772 torr at 2000 K .

Part A: Calculate the equilibrium partial pressure of CO2 .

Part B: Calculate the equilibrium partial pressure of H2 .
