Find `DeltaG^(@)andDeltaH^(@)` for the reaction
`CO(g)+(1)/(2)O_(2)(g) toCO_(2)(g)at 300K`
when the standard entropy is `-0.094kJ mol^(_1)K^(-1).` The standard Gibbs free energiers fo formation for `CO_(2)andCOare-394.4 and-137.2kJ mol^(-1) respectively.`

A

`Delta G^(@) = 257.2 kJ/mol, Delta H^(@) = 285.4 kJ/mol`

B

`Delta G^(@) = 514.4 kJ/mol, Delta H^(@) = -570.8 kJ/mol`

C

`Delta G^(@) = +514.4 kJ/mol, Delta H^(@) = 570.8 kJ/mol`

D

`Delta G^(@) = -257.2 kJ/mol, Delta H^(@) = -285.4 kJ/mol`

Text Solution

Verified by Experts

The correct Answer is:
D

`Delta G^(0) = sum G_(R)^(0) = -394.4 - (-137.2) = -257.2 KJ//mol`
