In the Gibbs energy equation is "s" the symbol for entropy?

No.

ss is not the symbol for entropy. Sometimes, ss is used for specific heat capacity in "J/g"cdot"K"J/gK:

q = msDeltaT

where:

  • q is heat flow in "J". In is positive, and out is negative.
  • m is mass in "g".
  • DeltaT is change in temperature in "K" or ""^@ "C".

Entropy, however, is featured as ul(ul(S)):

\mathbf(DeltaG = DeltaH - TDeltaS)

where:

  • DeltaG is the Gibbs' Free Energy in "kJ/mol".
  • DeltaH is the enthalpy in "kJ/mol".
  • T is the temperature in "K".
  • DeltaS is the entropy in "J/K"cdot"mol".

The capitalization matters.
