Explanation:

In a reversible reaction, the reactants can form products, and the products can also react to form the reactants. At equilibrium, the rate of the forward reaction is equal to the rate of the backward reaction.

When a reversible reaction reaches equilibrium, both the forward and backward reactions continue to occur, but at equal speeds. This means that the number of reactant molecules converting into product molecules is the same as the number of product molecules converting back into reactant molecules.

Key Points:
- Equilibrium is reached when the rates of the forward and backward reactions are equal.
- The concentrations of the reactants and products at equilibrium do not have to be equal, but their ratios do not change.
- Equilibrium is a dynamic state, where reactants are continuously converting into products and vice versa, but there is no net change in the concentration of the reactants and products.
- Equilibrium can be reached from either direction, depending on the conditions (such as temperature, pressure, and concentrations of reactants and products).
- The position of equilibrium can be shifted by changing the conditions of the system, such as by changing the temperature, pressure, or concentrations of reactants and products.

I think the answer of this question will be C. I have done it from a example that if you put and drain water at same speed from a tank filled with water then only the equilibrium can be maintained or the amount of water can not be increased nor decreased.

Not all chemical reactions proceed to a stage at which the concentrations of the reactants become vanishingly small. Here we consider the kinetics of such reactions.Let a reaction be represented in general terms by the schemewhere k., and k_., represent the rate constants for the forwards and reverse reactions, respectively. The equilibrium constant for this reaction may be written asK = [B] /[A] = K1/K1 --(1)where the subscript 00 refers to a time t, sufficiently long to establish equilibrium at the given temperature. The initial concentration of species A is [A]O, and that of B is [B]O . After a time t, let the concentration of species A be [A/t and that of B be [Bat. The total rate of change of [At is given byd[A]t/dt= - K1[A]t + k-1[B]tIf, as is usual, [B]O is initially zero, it follows from a mass balance that at any time t,[Bat = [A]0 - [A]t, whenced[A]t/dt = K1[A]t + k-1([A]O - [A]t)ord[A]t/dt = (K1 + k-1)At what time is the rate of change of concentration of A equal to rate of change of concentration of C in magnitude ?
