1.

Assertion. If beta_(4) for [Cu(NH_(3))_(4)]^(2+) is 2.1xx10^(13), its instability constant is 4.76xx10^(-14). Reason. Overall dissociation equilibrium constant varies inversely with formation constant.

Answer»

If both assertion and REASON are true, but reason is not the true explanation of the assertion
If both assertion and reason are true, but reason is not the true explanation of the assertion
If assertionis true, but reason is false
If both assertion and reason are false

Solution :R is the CORRECT explanation of A.
Dissociation constant (instability constant)
`=(1)/("Formation constant "beta_(4))`
`=(1)/(2.1xx10^(13))=4.76xx10^(-14)`
