For a gaseous reaction `A+3BhArr 2C,DeltaH^(@)=-90.0kJ, DeltaS^(@)=-200.0jk^(-1)` AT `400k.` The `DeltaG^(@)` for the reaction `(1)/(2)A+(3)/(2)B rarr C` at `400K` is `:`

Answer» Correct Answer - 5
For, `A+3BhArr 2C`
`DeltaG^(@)=DeltaH^(@)-TDeltaS^(@)`
`=-90-400xx(-0.200)`
`=-90+80=-10kJ`
For, `(1)/(2)A+(3)/(2)B hArrC`
`DeltaG^(@)=-5kJ`
