At 50 C (celcius), Kc = 2.2 x 10^3 for the reaction 3 Fe (s) + 4 H2O (g) ? Fe3O4 (s) + 4 H2 (g) What is the value of Kp at 200oC for this reaction? A) 8.8 x 103 B) 2.2 x 103 C) 5.5 x 102 D) 3.5 x 104 E) This question cannot be answered with the information provided

At 1050 K, Kp = 0.900 for the following reaction: H2 (g) + CO2 (g) ? H2O (g) + CO (g) If 0.200 atm of H2 and 0.200 atm of CO2 are admitted into a rigid container and allowed to reach equilibrium, what should the equilibrium partial pressure of CO be (in atm) ?
