Assertion (A) : K(p) can be equal to or ...

Assertion (A) : `K_(p)` can be equal to or less than or even greater than value of `K_(c)`
Reason (R) : `K_(p)=K_(c)(RT)^(Deltan)`
Relation between `K_(p)` and `K_(c)` depends on the change in the number of moles of gaseous reactants and products.

A

If both (A) and (R) are correct, and (R) is the correct explanation for (A)

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A)

C

If (A) is correct, but (R) is incorrect

D

If (A) is incorrect, but (R) is correct.

Text Solution

Verified by Experts

The correct Answer is:
A
`K_(p)=K_(c )(RT)^(Deltan)`
When `Deltan gt 1, K_(p) gt K_(c )`
When `Deltan lt 1, K_(p) lt K_(c )`
When `Deltan=0, K_(p)=K_(c )`
