We know that the relationship between K(...

We know that the relationship between `K_(c)andK_(p)` is `K_(p)=K_(c)(RT)^(Deltan)`
What would be the value of `Deltan` for the reaction :
`NH_(4)Cl_((s))hArrNH_(3(g))+HCl_((g))?`

A

1

B

0.5

C

1.5

D

2

Text Solution

Verified by Experts

The correct Answer is:
D
For the reaction :
`NH_(4)Cl_((s))hArrNH_(3(g))+HCl_(g)`
`Deltan=n_(("gaseous products"))-n_(("gaseous reactants"))=2-0=2`
