Chemistry Equilibrium

Question

C (s) + H₂O(g) -> CO(g) + H₂(g) Kp=1.6x10^-21 at 298

 If at 298 K

 P_CO= 1x10^-8 atm P_H2= 2x10^-4 atm P_H2O= 5x10^-5 atm and mass of C = 2g

Is the mix‎ture of gases at e‎quilibrium ? S‎how calculations.

If n‎ot, wh‎ich direc‎tion will the reac‎tion proc‎eed to rea‎ch equilibr‎ium?

Answer 1

Calculate the Q, which is the K expression for the starting conditions. Q = K value, equil. Q<K reaction will proceed towards products. Q >K reaction proceeds towards reactants.

Q = P_H2P_CO/P_H2O for inittial conditions.
