A balanced chemical equation is a chemist's shortcut for representing the molecules and atoms involved in a chemical process using chemical symbols. On the left side of the equation are the reactants, and on the right are the products. The number of molecules involved is indicated by the coefficients, and the number of atoms in each molecule is indicated by the subscripts.
Based on the interactions of the constituent chemicals, knowledge of the law of conservation of mass, and practise with a few example equations, chemical equations can be "balanced," much like algebraic equations.

Answer : The value of equilibrium constant for this reaction at 328.0 K is
Explanation :
As we know that,
where,
= standard Gibbs free energy = ?
= standard enthalpy = 151.2 kJ = 151200 J
= standard entropy = 169.4 J/K
T = temperature of reaction = 328.0 K
Now put all the given values in the above formula, we get:
The relation between the equilibrium constant and standard Gibbs free energy is:
where,
= standard Gibbs free energy = 95636.8 J
R = gas constant = 8.314 J/K.mol
T = temperature = 328.0 K
K = equilibrium constant = ?
Now put all the given values in the above formula, we get:
Therefore, the value of equilibrium constant for this reaction at 328.0 K is
