CAIE A-Level Chemistry A2 23.4.1 The Gibb…ation G

[Maximum number: 1]

For a particular gas phase reaction the variation in standard Gibbs free energy change, $\Delta G^{\ominus}$ , with temperature is shown.

Assume standard enthalpy change, $\Delta H^{\ominus}$ , and standard entropy change, $\Delta S^{\ominus}$ , remain constant with temperature.

Figure for Question 1 — CAIE A-Level Chemistry A2

Write the equation that relates $\Delta G^{\ominus}$ to $\Delta H^{\ominus}$ and $\Delta S^{\ominus}$ .

$\Delta G^{\ominus} = \Delta H^{\ominus} - \mathrm{T}\Delta S^{\ominus}$
