The process depicted in the given figure is to be identified as being spontaneous at high temperature or low temperature, or being unaffected by changing temperature. Concept introduction: Entropy is a thermodynamic property which shows the randomness or disorder of the atoms within the system. The randomness of the molecules increases when solid is melted and liquid is converted into vapor state. As in vapor state particles move freely because they are at larger distances from each other. In a spontaneous process, the entropy of the system increases when one phase changes to another phase in an isolated system according to second law of thermodynamic. When the temperature is increased or decreased, the entropy of a system also changes. To identify: The process depicted in the given figure as being spontaneous at high temperature or low temperature, or being unaffected by changing temperature.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments. This especially applies to the reactions in…
