A change in the free energy of a system at constant temperature and pressure will be:
`Delta_(sys)G = Delta_(sys)H -T Delta_(sys)S`
At constant temperature and pressure
`Delta_(sys) G lt 0` (spontaneous)
`Delta_(sys)G = 0` (equilibrium)
`Delta_(sys)G gt 0` (non-spontaneous)
If both `DeltaH` and `Deltas` are negative, the reaction will be spontaneous

Options

A. At high temperature
B. At all temperatures
C. At low temperature
D. At high pressure

Explanation

`DeltaC = DeltaH - T Deltas`
