For the reaction:
`2H_(2(g))+O_(2(g))iff2H_(2)O_((g))`
Which of the following fact holds good?

A

`K_(p)=K_(c )`

B

`K_(p)gtK_(c )`

C

`K_(p)ltK_(c )`

D

`K_(p)andK_(c )` cannot be correlated

Text Solution

Verified by Experts

The correct Answer is:
C
As we know, `K_(p)=K_(c)(RT)^(Deltan)`
`2H_(2(g))+O_(2(g))iff2H_(2)O_((g))`
`Deltan=2-(2+1)=-1`
`K_(p)=K_(c)(RT)^(-1)=(K_(c))/(RT)`
Hence, `K_(p)ltK_(c)`
