Gujarat BoardEnglish MediumSTD 11 ScienceNEETSTD 11 - 6.1. Equilibrium - 1 (chemical Equilibrium)4 Marks
MCQ
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 correct and the Reason is a correct explanation of the Assertion.
  • B
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • ✓
    If the Assertion is correct but Reason is incorrect.
  • D
    If both the Assertion and Reason are incorrect.
✓

Answer

Correct option: C.
If the Assertion is correct but Reason is incorrect.
c
The equilibrium constant has a fixed value for every reaction at a particular temperature. However composition of final equilibrium mixture at a particular temperature does not depend upon the starting amount of reactant. Hence, assertion is true but reason is false.
