What is Reaction Gibbs energy?

Also known as: standard reaction Gibbs energy

Definition 2.10 University Chemistry — Year 2 · Chapter 2 — Entropy and Free Energy of Reaction

The reaction Gibbs energy is ΔrG=(∂G/∂ξ)T,p\Delta_r G = (\partial G/\partial\xi)_{T,p}, and the standard reaction Gibbs energy is ΔrG∘(T)=∑iνiGm,i∘(T)\Delta_r G^\circ(T) = \sum_i\nu_iG^\circ_{m,i}(T), both in kJ/mol\mathrm{kJ}/\mathrm{mol}.
