Explanation / Answer

3) Equilibrium is a special case of reversible reaction. When the rate of forward reaction and the rate of backward reaction becomes equal to each other the reaction is said to be in equilibrium. This is a state of dynamic equilibrium, as reaction never stops there, rather a rapid interconversion of reactant to product and product to reactant takes place such that the concentration of reactant and product remains constant.

which is not true is - (A) all reactions have stopped
