At a certain temperature, the equilibrium constant K for the following reaction is 819.: H2(g) + Cl2(g) = 2 HCI(g) Use this information to complete the following table. O There will be very little H2 and Cl2. Suppose a 6.0 L reaction vessel is filled with 0.29 mol of HCI. What can you say about the composition of the mixture in the vessel at equilibrium? There will be very little HCl. Neither of the above is true. What is the equilibrium constant for the following reaction? Round your answer to 3 significant digits. K = 2 HCl(9) H2(9)+C12(9) What is the equilibrium constant for the following reaction? Round your answer to 3 significant digits. K = [ 3 H (9)+3C12(9) 6 HCl(9)
