Q59 / 180 · AIIMS 2010 · Chemistry

Assertion : The equilibrium constant is fixed and a characteristic for any given chemical reaction at a specified temperature. Reason: The composition of the final equilibrium mixture at a particular temperature depends upon the starting amount of reactants.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion
  • Correct answer
    B
    If both assertion and reason are true but reason is not the correct explanation of assertion
  • C
    If assertion is true but reason is false
  • D
    If both assertion and reason are false.

Solution

The equilibrium constant is always fixed and is characteristic of a reaction at specified temperature. However final composition of a reaction mixture at equilibrium at constant temperature depends on the initial concentration of reactants and products.

Hence, the correct answer is option: 'B'.
