Short Answer TypeWhat is the significance of equilibrium constant?
(i) The numerical value of equilibrium constant is a measure of the extent to which reactants have been converted into the products. A large value of K indicates that reactants have been converted to the products to a large extent. The lower value of K indicates that only small amounts of reactants have been converted into products.
(ii) If we know the initial concentration of reactants and equilibrium constant of the reaction, we can calculate the equilibrium concentration of various reactants and products.

At a given time the composition of reaction mixture is 
In which direction the reaction will proceed?
A mixutre of 1.57 mol of N2, 1.92 mol of H2 and 8.13 mol of NH3 is introduced into a 20L reaction vessel at 500K. At this temperature, the equilibrium constant, Kc, for the reaction
is 
. Is the reaction mixture at equilibrium? If not, what is the direction of the net reaction?
is at equilibrium at 1300K in a 1 L flask. It also contains 0.30 mol of CO, 0.10 mol of H2 and 0.02 mol of H2O and an unknown amount of CH4 in the flask. Determine the concentration of CH4 in the mixture. The equilibrium constant, Kc, for the reaction at the given temperature is 3.90.What is Kc for the following equilibrium when the equilibrium concentration of each substance
