The standard entropy change of the reaction is negative .
Given ,
For the reaction depicted in the molecular scenes , X is red and Y is green .
through observing the scenes , the balanced chemical equation of the scenes is given by ,
3X2 + 9Y2 → 6XY3
The reaction representation indicates that there are 12 reactant molecules which gives 6 product molecules .here the degree of disorderness of molecules decreases from reactants to the products and thus the entropy decreases during the reaction .
The standard entropy of the reaction is given by ,
ΔS°rxn = sum of the S°(products ) - sum of the S°(reactants )
Therefore , the sign of the entropy change of the reaction is negative .
What is a balance chemical reaction ?
A balanced chemical reaction is a type of reaction which include the reactants and products in same amount i.e. the no of mole on both side of the reaction is remains same or balanced .
