When the equilibrium is attained, the concentration of each of the reactants and products becomes equal.

Assertion : Equilibrium is dynamic in nature. Reason: The concentrations of reactants and products become equal at equilibrium

Assertion (A) : Chemical equilibrium represents a state of a reversible reaction in which measurable properties of the system ( pressure, concentration , colour etc.) become constant under the given set conditions. Reason (R ) : A chemical equilibrium is attained when the concentrations of the reactants become equal to the concentrations of the products.

Which statement characterize a chemical system at equilibrium ? (P)the rate of the forward reaction is equal to the rate of the reverse reaction (Q)The concentrations of the reactants and products are equal.

In which of the following reactions, will the equilibrium mixture contain an appreciable concentration of both reactants and products.

The initial molar concentration of the reactants A and B were 0.1 M and 0.2 M respectively in the following reaction A+B hArr 2C When equilibrium was attained the concentration of A in the reaction mixture was found to be 0.06M . Calculate the equilibrium constant.

Assertion : The equilibrium constant for the reverse reaction is equal to the inverse of the equilibrium constant for the forward reaction . Reason : The value of equilibrium constant is independent of initial concentrations of the reactants and products.

At equilibrium, the rate of forward and backward reaction become equal and as a result concentration of each reactant and product becomes constant. The expression and numerical value of equilibrium constant depends upon the form of balanced chemical equation. If stoichiometry of the balanced chemical equation changes, the value of equilibrium constant changes. An equilibrium system for the reaction: N_2O_4(g) hArr 2NO_2(g) at 390 K. in a 5L flask contains 1.0 mol of NO_2 and 0.125 mol of N_2O_4 . What happens to an equilibrium in a reversible reaction if catalyst is added to it?
