For a hypothetical process,$\mathrm{A}\to \mathrm{B}$, predict whether the process is spontaneous or not when $\mathrm{\Delta H}=–\mathrm{ve}$, $\mathrm{T\Delta S}=–\mathrm{ve}$and $\mathrm{T\Delta S}>\mathrm{\Delta H}$.

Write Gibbs' Helmholtz equation which relates the enthalpy change and the energy change of a process at constant temperature and pressure. Explain the effect of temperature on feasibility for exothermic process in terms of Gibbs' Helmholtz equation.
