For the reaction depicted in the molecular scenes, X is red and Y is green. (b) Determine the sign of \Delta S_{\mathrm{rxn}} .

Respuesta :

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 .
