Interpretation:
To write an equilibrium expression for given equilibrium reaction.
Concept Introduction:
Equilibrium reaction:
A
Or
Equilibrium expression:
It denotes the ratio of product and reactants in concentration term that is expressed by K (equilibrium constant).
Consider an equilibrium reaction:
Here, a, b, c and d are coefficient.
So, the equilibrium expression for above reaction would be.
