Assertion: If 4 for [Cu(NH3)4] 2+ is 2.1 × 10 13, its instability constant is 4.76 × 10 –14. Reason: Overall dissociation equilibrium constant varies inversely with formation constant. [AIIMS2010]
A.Both Assertion and Reason are true and Reason is✓ Correct
B.Both Assertion and Reason are true but Reason is
C.Assertion is true but Reason is false.
D.Both Assertion and Reason are false.
Explanation
The overall complex dissociation constant or instability constant is the reciprocal of the overall stability constant 4 β -14 13 4 1 1 = =4.7×10 β 2.1×10 Hence, the correct option is (a)
