The Gibbs energy is a thermodynamic function of state defined by

G = H - TS

where H is the enthalpy (Joules), T is the absolute temperature (Kelvins), and S is the entropy (Joules per Kelvin).

G=H-TS
G is gibbs energy.
H is change in enthalphy.
T is temperature difference.
S is entropy change (randomness)
If "G" is negative the process is a spontaneous process otherwise it is a non-spontaneous process.
One should make appropriate change in the signs of H,T and S to make the process spontaneous
i.e, sign should be negative.
