The equilibrium constant Kp for the reaction 2H2O(g)--> 2H2(g)+O2(g) is 2x10^-42 at 25 degrees C. (a) what is Kc for the reaction at the same temperature? (b) the very small value of Kp (and Kc) indicates that the reaction overwhelmingly favors the formation of water molecules. Explain why, despite this fact, a mixture of hydrogen and oxygen gases can be kept at room temperature without any change.

Is it possible for a reaction to have a large equilibrium constant but small forward and reverse rate constants? Choose one - A. No, the equilibrium constant and rate constant are both determined by the same thermodynamic parameters. B. Yes, the equilibrium constant is determined by the ratio of the forward and reverse rate constants, not the absolute value of those rates C. No, a large equilibrium constant means that the rate constants must also be large D. Yes, the...
