correct option is (c) the rates of forward and reverse reactions become equal.
A state is said to be in chemical equlibrium if forward and reverse reactions occur at equal rates or we can say in equilibrium concentration of reactants and products becomes constant not equal which does not vary.
option (a) is incorrect because reaction do not stop at equilibrium.
option (b) is incorrect because at equilibrium, no reaction stops, neither forward nor reverse.
option (d) is incorrect, because at equilibrium concentration of reactsnt and product becomes constant not equal.
option (e) is incorrect, because with tenperature change, equilibrium shifts in a direction.

Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. As a reaction proceeds backwards toward equilibrium the reactant concentrations rise. As a reaction proceeds backwards toward equilibrium the reverse rate drops. As a reaction proceeds forward toward equilibrium the product concentrations rise. At equilibrium concentrations of reactants and products stay constant. At equilibrium there are always equal amounts of reactants and products.

Which of the following statements is/are CORRECT? For a chemical system at equilibrium, the forward and reverse rates of reaction are equal. For a chemical system at equilibrium, the concentrations of products divided by the concentrations of reactants equals one. For a chemical system, if the reaction quotient (Q) is less than K, reactant must be converted to products to reach equilibrium.

Which of the following statements is true about chemical equilibrium? Select all that apply. At chemical equilibrium, the reactants have been completely consumed. At chemical equilibrium, both reactions stop completely. At chemical equilibrium, the concentrations of the species involved in the reaction stay constant (in the absence of an external perturbation). At chemical equilibrium the rate of the forward reaction is equal to the rate of the reverse reaction.
