Temperature of equilibrium

4.11.8

Temperature of equilibrium

For equilibrium, ΔG=ΔH−TΔS\Delta G = \Delta H - T\Delta S gives

∴ T=ΔHΔS...(4.41)\therefore\ T = \frac{\Delta H}{\Delta S} \qquad \text{...(4.41)}

TT is the temperature at which the changeover from spontaneous to nonspontaneous behavior occurs. ΔH\Delta H and ΔS\Delta S are assumed to be independent of temperature in Eq. (4.41). Introducing the temperature dependence of ΔH\Delta H or ΔS\Delta S w …
