Statement: Concentration of the reactant and product does not change with time at equilibrium for a chemical reaction.
Explanation: The rate of a reaction is zero at equilibrium.

A : At equilibrium concentration of the reactant and product does not change with time for a chemical reaction. R : The rate of reaction is zero at equilibrium

The rate of a zero reaction does not change with time. Explain.

Assertion: At equilibrium the concentration of all reactants and products are equal. Reason : At equilibrium , the rate of forward reactions is equal to the rate of backward reactions.

At chemical equilibrium , the concentration of all reactants and products are equal

For a reversible reaction, if the concentrations of the reactants are doubled, then the equilibrium constant value
