Equilibrium Constant

of a reaction is given by the expression.

...(i)

Given,
or

on putting the values in Eq (i)


or

Now, as the reaction is at equilibrium, hence .

Given reaction,

Enthalpy
Entropy
Temperature
We know that, Gibbs free energy ;
$?G^??= ?H^??- T?S^??


Further,



Antilog

Given reaction :
(i)
Equilibrium constant
(ii)
Equilibrium constant
(iii)
Equilibrium constant
So,
