Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): For an equilibrium reaction, if all stoichiometric coefficients of the balanced chemical equation are multiplied by 2, the new equilibrium constant becomes the square of the original equilibrium constant. Reason (R): The numerical value of the equilibrium constant for a reaction depends on the stoi

Options

  1. ABoth (A) and (R) are true and (R) is the correct explanation of (A)
  2. BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
  3. C(A) is true but (R) is false
  4. D(A) is false but (R) is true

Correct answer

A. Both (A) and (R) are true and (R) is the correct explanation of (A)

Step-by-step solution

The equilibrium constant expression is written by raising the active masses of reactants and products to the power of their respective stoichiometric coefficients. Thus, the numerical value of the equilibrium constant depends on the stoichiometric representation of the balanced chemical equation. Therefore, (R) is true. When all stoichiometric coefficients of a balanced chemical equation are multiplied by a factor of 2, the new equilibrium constant is the original equilibrium constant raised to the power of 2 (i.e.
