Assertion : The equilibrium constant for...

Assertion : The equilibrium constant for the reaction `CaSO_(4).5H_(2)O(s)hArrCaSO_(4).3H_(2)O(s) + 2H_(2)O(g)` is
`K_(C) = ([CaSO_(4).3H_(2)O][H_(2)O]^(2))/([CaSO_(4).5H_(2)O])`
Reason : Equalibrium constant is the ration of the product of molar concentration of the substance produced to the product of the molar concentrations of reactants with each concentrations term raised to the power equal to the respective stoichiometric constant.

A

If both assertion and reason are true and reason is the correct explanation of the assertion.

B

If both assertion and reason are true and reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Assertion is false but reason is true.
`K_(c) = [H_(2)O]^(2)`, because concentration of solids is taken to be unity.
