Question

A positive ΔH and positive ΔS:

A. will never produce a spontaneous reaction
B. will always produce a spontaneous reaction
C. will only produce a spontaneous reaction if the increase in entropy times temperature is greater than the increase in enthalpy
D. will only produce a spontaneous reaction if the increase in enthalpy is greater than - T times the increase in entropy

Answer 1

consider the equation \(\Delta G=\Delta H - T\Delta S\)

when \(\Delta G<0\) the reaction is spontaneous in the forward direction
when \(\Delta G>0\) the reaction is non-spontaneous in the forward direction
