Chemical equilibrium (K) is defined as ratio of product of concentration of products, raised to suitable power, to product of concentration of reactants, raised to suitable power. The concept of equilibrium constant is application to reversible reactions.
In the reaction system,
cC + hH ↔ eE + mM
Equilibrium constant is expressed as,
K =
![([E]^e[M]^m)/([C]^c[H]^h)](https://img.qammunity.org/2019/formulas/chemistry/high-school/truu7of7gpuonsp8er2j020fgxy4y75w7h.png)
