Entropy is positive when

WebMay 8, 2024 · This condition describes an endothermic process that involves a decrease in system entropy. In this case, ΔG will be positive regardless of the temperature. Such a process is nonspontaneous at all temperatures. ΔH is negative and ΔS is positive. This condition describes an exothermic process that involves an increase in system entropy.
