Which of the following is true for the equilibrium constant of a reaction? its value remains constant at different temperatures. it is a ratio of coefficients of reactants to products. it is represented by the symbol k. its value is always less than 1.

Option (c) is the correct answer.

Explanation:

Equilibrium reaction means when rate of forward reaction is equal to rate of backward reaction.

And, relationship between the amount of products and the amount of reactants present in an equilibrium reaction at a given temperature is known as equilibrium constant.

Equilibrium constant is denoted by 'K'.

For example,

The equilibrium constant for this reaction will be as follows.

           K =

Therefore, it is the ratio of products to reactants. And, if value of K > 1 then it means that the mixture contains mostly products whereas K < 1 means that the mixture contains mostly reactants.

Hence, we can conclude that out of the given options it is represented by the symbol K, is true for the equilibrium constant of a reaction.
