Equilibrium Constant in a Reversible Chemical Reaction

The equilibrium constant (Kc) is a measure of the extent to which a reversible chemical reaction proceeds at a given temperature. Kc is defined as the ratio of the concentrations of the products to the concentrations of the reactants when the reaction reaches equilibrium at a particular temperature.

Kc = [Products] / [Reactants]

The equilibrium constant depends on the stoichiometry of the reaction and the temperature at which the reaction occurs. It does not depend on the initial concentrations of the reactants.

Explanation of the Correct Answer

Option 'C' is the correct answer. The equilibrium constant does not depend on the initial concentrations of the reactants. This is because the equilibrium constant is defined as the ratio of the concentrations of the products to the concentrations of the reactants when the reaction reaches equilibrium. At equilibrium, the concentrations of the reactants and products are constant, and the equilibrium constant is a fixed value for a given reaction at a particular temperature.

Importance of Equilibrium Constant

The equilibrium constant is an important parameter in chemistry because it provides a quantitative measure of the extent to which a chemical reaction proceeds. A high value of Kc indicates that the reaction proceeds to a greater extent, while a low value of Kc indicates that the reaction does not proceed to a significant extent. The value of Kc also provides information about the direction of the reaction at equilibrium. If the value of Kc is greater than 1, the reaction proceeds predominantly in the forward direction, while if the value of Kc is less than 1, the reaction proceeds predominantly in the reverse direction.

Conclusion

The equilibrium constant is a measure of the extent to which a reversible chemical reaction proceeds at a given temperature. The value of Kc depends on the stoichiometry of the reaction and the temperature at which the reaction occurs. It does not depend on the initial concentrations of the reactants. The equilibrium constant provides important information about the direction and extent of a chemical reaction at equilibrium.

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)For the reaction (having both 1ts order reactions), the concentration as a function of time are given for a certain experimental run along with a tangent to the graph at the origin. The ratio of the magnitude of the slopes of the graph of [A/ and [C/ at the origin would be
