Question

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

Answer 1

No.

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

`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.
