For a chemical reaction, DeltaG will always be negative if

Answer»

`DeltaH` and `TDELTAS` both are positive
`DeltaH` and `TDeltaS` both are negative
`DeltaH` is negative and `TDeltaS` is positive
`DeltaH` is positive and `TDeltaS` is negative

Solution :Gibbs-Helmholtz EQUATION is as FOLLOWS :
`DeltaG=DeltaH-TDeltaS`
From Gibbs-Helmholtzequation, it is clear that `DeltaG` will ALWAYS be negative, if `DeltaH` is negative and `TDeltaS` is positive.
