Question

how to calculate equilibrium constant?​

Answer 1

Answer:

Calculating Equilibrium Constants

We need to know two things in order to calculate the numeric value of the equilibrium constant:

the balanced equation for the reaction system, including the physical states of each species. From this the equilibrium expression for calculating Kc or Kp is derived.

the equilibrium concentrations or pressures of each species that occurs in the equilibrium expression, or enough information to determine them. These values are substitued into the equilibrium expression and the value of the equilibrium constant is then calculated.
