What is a Spontaneous charge

This means a release of free energy from the system corresponds to a negative change in free energy, but to a positive change for the surroundings.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

dynamic equilibrium is the answer.
