Calculate `DeltaG^(Theta)` for the conversion of oxygen to ozone, `((3)/(2)) O_(2)(g) hArr O_(3)(g) at 298 K`, of `K_(p)` for this conversion is `2.47 xx 10^(-29)`.

A

`163 "kJ mol"^(-1)`

B

`2.4 xx10^(2) "kJ mol"^(-1)`

C

`1.63 "kJ mol"^(-1)`

D

`2.38 xx 10^6 "kJ mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
As we know that, `DeltaG^@ =-2.303RTlogK_p`
Therefore, `DeltaG^@ =-2.303 xx(8.314) xx(298) (log 2.47 xx10^(-29))`
`DeltaG^@ =16,3000 "J mol"^(-1)=163 "KJ mol"^(-1)`
