Which of the following statement is/are false ?

Answer»

`Delta_rS` for `1/2Cl_2(g)toCl(g)` is POSITIVE
`DeltaElt0` for combustion of `CH_4(g)` in a sealed container with rigid adiabatic system
`DeltaG` is always ZERO for a REVERSIBLE process in a closed system
`DeltaG^@` for an ideal gas reaction is a FUNCTION of PRESSURE

Solution :`(A)Cl_(2_(g))to2Cl_((g)) " " ` randomness is increasing
(B) In closed container `DeltaV=0` hence work cone is zero.
There is no heat exchange . Hence `DeltaE=q+W=0`
( C)`DeltaG` will be zero only when equilibrium is reached.
`:.` not a function of pressure
(D)`DeltaG^@= - RT` In `K_(eq)`
`:.` not a function of pressure
