gibbs free energy equation to determine whether a reaction would be spontaneous

We have learnt that of DG is a measure of the spontaneity of a chemical reaction. It can be shown that the free energy of a process is equal to maximum possible work that can be derived from the proces..

We have learnt that of D G is a measure of the spontaneity of a chemical reaction. It can be shown that the free energy of a process is equal to maximum possible work that can be derived from the process as given below: From first law of thermodynamics, it is..

In order to find out some other factor that may be responsible for the feasibility of a process, let us examine endothermic reactions. The simplest process occurring without any energy change (where D H is almost zero) may be illustrated with the help of following experiment. fi..

It is a well-known fact that all physical and chemical processes are accompanied by energy changes. It is possible to interpret various spontaneous processes on the basis of changes in energy. Consider the spontaneous processes such as falling of a cricket b..

(i) Once a reaction between hydrogen and oxygen is initiated by passing electric spark through it, then it occurs itself spontaneously even at room temperature. (ii) In domestic oven, coal (carbon) keeps on burning once initiated ignition (iii) Methane burns with oxygen onc..

There are a number of endothermic reactions ( D H, positive), which are known to be spontaneous. A few examples of such processes are given below: i) Evaporation of water is an endothermic process but it is spontaneous in nature. ii) Dissolution of ammonium chloride..
