The state at which the concentrations of reactants and products do not change with of a chemical reaction is known as chemical equilibrium. When the reactants are mixed together in a vessel, the whole reactants do not completely converted into products. After some time the ...

Mathematically, G = H – TS At constant temperature, ∆G = ∆H - T∆S Hence two factors contribute to the value of free energy ∆G. One is energy factor ∆H and the other is entropy factor T∆S. Both the factors are necessary for calculating the spontaneity of the reaction. The ...

If the free energy change i.e. ∆G of a chemical reaction is positive, the reaction would not proceed. If the free energy change i.e. ∆G of a chemical reaction is negative, the reaction would be spontaneous i.e. feasible. If the free energy change i.e. ∆G ...

Spontaneous reaction is those which proceed at very fast rate. A chemical reaction which is accompanied by evolution of heat is known as exothermic reaction. Spontaneous reactions are also known as exothermic reactions. In the exothermic reactions internal energy change has negative sign at constant ...
