Final answer:
In chemistry, a chemical reaction proceeding to equilibrium is considered as a spontaneous change. Equilibrium is a dynamic state where reactions are still occurring, and it is characterized by a balance between the forward and backward processes.
Step-by-step explanation:
In chemistry, a chemical reaction proceeding to equilibrium is considered as a spontaneous change.
When a reaction reaches equilibrium, it means that the forward and reverse reactions are happening at the same rate, and the concentrations of reactants and products do not change. Although the concentrations may not be equal, they are constant.
Equilibrium is a dynamic state where reactions are still occurring, and it is characterized by a balance between the forward and backward processes.
