From the given set of graphs, the graph that depict the G s y s changes for H I formation has to be identified. Concept introduction: Entropy S : it is used to describe the disorder. It is the amount of arrangements possible in a system at a particular state. Entropy S : it is used to describe the disorder. It is the amount of arrangements possible in a system at a particular state. ΔS univ = ΔS sys + ΔS surr Any natural process or a chemical reaction taking place in a laboratory can be classified into two categories, spontaneous or nonspontaneous. Spontaneous process occurs by itself, without the influence of external energy. In spontaneous process the free energy of the system decreases and entropy of the system increases. Nonspontaneous process requires an external influence for initiation. In nonspontaneous process the free energy of the system increases but entropy of the system decreases.

Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.

Entropy is a thermodynamic quantity, which is the measure of randomness in a system. The term entropy is useful in explaining the spontaneity of a process. For all spontaneous process in an isolated system there will be an increase in entropy. Entropy is represented by the letter ‘S’. It is a state function. The change in entropy gives information about the magnitude and direction of a process. The entropy of one mole of substance at a given standard state is called standard molar entropy (So).
