Interpretation: The equilibrium constants for the given reactions are to be calculated.
Concept introduction: The equilibrium constant
Partial pressure of a gas is defined as the pressure applied by the each gas to the surroundings.
The equilibrium constant depends upon temperature.
At equilibrium sum of all the partial pressure is equal to the total pressure.
Law of mass action is applicable on the equilibrium reactions.
Law of mass action states that at a given temperature the equilibrium constant is equal to the partial pressure of the products to the reactants raised the power of
