In order to perdict variation of Gibbs free energy with progress of reaction at constant temperature and 1 bar pressure, it is important to know realtive stability of the components involved in chemical reaction at standard useful work then the change in Gibbs free energy should be calculated In the thermite reaction used obtaining energy, aluminium oxide. From the given data identify the option 9s) which is (are) correct. [Given : DeltaH_(f)^(@)Al-(2)O_(3)=-390kj//mol, DeltaH_(f)^(@)Fe_(2)O_(3)=-176kj//mol, Density of aluminimum = 2/7 gm/ml, Density of Fe_(2)O_(3)=3.2gm//ml
