Thermodynamics stability is often used in chemical reactions to predict extent of reaction or to predict the preferred product in some reaction. Thermodynamically amore stable substance will be the one which has lower Gibb's free energy.In various cases,it might be decided on the basis of enthalpy, however , that may not always be true. The thermodynamic data Therefore can be used for prdicting stability among isotopes and to decide the possible transformation.Based on this information and the data given below, answer the questions that follow.

Answer» Transformation from white tin to GREY tin occurs changing it to a more BRITTLE form There will be a contraction in volume observed due to the ALLOTROPIC change The reaction will slow down after after initiation The objects will become STRONGER ANSWER :A
