Question

why we say that in equilibrium rate of reverse direction are equal but concentration of product and reactant may or may not be equal why so explain concept briefly in 2-3 lines I don't want Encyclopaedia of it aur Wikipedia copy paste I want to the point answer otherwise han​

Answer 1

Reversible reactions that happen in a closed system eventually reach equilibrium. At equilibrium, the concentrations of reactants and products do not change. But the forward and reverse reactions have not stopped - they are still going on, and at the same rate as each other.
