During an endothermic chemical reaction, four moles of gaseous reactants are turned into two moles of gaseous products. a. Yes b. No c. Can't decide with information given.

Respuesta :

Manetho

Answer:

reaction is non spontaneous

Explanation:

In the question number of moles of decrease as the reactants turn into product

When  number of moles of gas decreases, the entropy also decreases (∆S= negative) and since process is endothermic (∆H=positive)

now,

ΔG= ΔH-TΔS

since, ΔS is negative and  ΔH the , ΔG will be positive as well. Since, ΔG is positive the reaction must be non-spontaneous.
