Relationships Between K And Chemical Equation

1)    When the reaction is written backward, the equilibrium constant is inverted.

                                             

2)    When the coefficients of an equation are multiplied by a factor, the equilibrium constant is raised to that factor.

3)    When you add equations to get a new equation, the equilibrium constant of the new equation is the product of the equilibrium constants of the old equations.

4)    When you subtract equations to get a new equation, the equilibrium constant of the new equation is the quotient of the equilibrium constants of the old equations.
