Detailed explanation-1: -Equilibrium is when the rate of the forward reaction equals the rate of the reverse reaction. All reactant and product concentrations are constant at equilibrium.

Detailed explanation-2: -At equilibrium: No further changes occur in the concentrations of reactants and products, even though the two reactions continue at equal but opposite rates. Eventually, the rates of the forward and reverse reactions become equal; the reactants form products at the same rate that the products form reactants.

Detailed explanation-3: -The amount of reactants and products do not have to be equal. However, after equilibrium is attained, the amounts of reactants and products will be constant.

Detailed explanation-4: -Reactions in which many reactants combine to give one product are called combination reactions whereas, in decomposition one reactant breaks down in many products.

Detailed explanation-5: -Chemical reactions are dynamic; they just do not go forward and stop. When the rate of product formation equals the rate of reactant production, the reaction is said to be at equilibrium.
