  • Match the following graphical variation with their description (i) (a) Variation in product concentration with time. (ii) (b) The reaction at equilibrium. (iii) (c) Variation in reactant concentration with time

Match the following graphical variation with their description

A B

(i)

 (a) Variation in product concentration with time
(ii)

(b) Reaction at equilibrium

 

(iii) 

 (c) Variation in reactant concentration with time

 

Answers (1)

(i) \rightarrow (c); (ii) \rightarrow (a); (iii) \rightarrow (b)

The variation of reactant concentration with time in a chemical reaction is as follows:

  • Reactant concentration decreases

    As the reaction proceeds, the number of reactant molecules decreases, which causes the concentration of the reactant to decrease. 

  • Reaction rate decreases

    As the concentration of reactants decreases, the reaction rate decreases. 

  • Product concentration increases

    As the reaction proceeds, the number of product molecules increases, which causes the concentration of the product to increase. 

  • Equilibrium

    When the concentration of the reactant and product become constant, equilibrium is established. This happens when the rates of the forward and backward reactions are equal.
