<Li> When ΔS> 0 and ΔH> 0, the process will be spontaneous at high temperatures and non-spontaneous at low temperatures . </Li> <Li> When ΔS <0 and ΔH <0, the process will be spontaneous at low temperatures and non-spontaneous at high temperatures . </Li> <P> For the latter two cases, the temperature at which the spontaneity changes will be determined by the relative magnitudes of ΔS and ΔH . </P> <P> When using the entropy change of a process to assess spontaneity, it is important to carefully consider the definition of the system and surroundings . The second law of thermodynamics states that a process involving an isolated system will be spontaneous if the entropy of the system increases over time . For open or closed systems, however, the statement must be modified to say that the total entropy of the combined system and surroundings must increase, or, </P>

What are the signs of δh δs and δg for the following spontaneous change
