S. Would the following reaction occur spontaneouslyi GfJ/mol ) at 298 K HCI g) 95.27 6. The AG for the following reaction is+5.40 k. What is the approximate AG value for this reaction at 100 C.? IAHom-57.9k, AS Q.177 7. The for the following reaction is 1.7 x 10" at 25.00 What is the AG for the reaction? 8 Sulfur dioxide present in polluted air reacts with oxygen when it passes over the catalyst in automobile catalytic converters. For this reaction, AG·-1.40 x 10,u/mol at 2S.00 oc what is the value of K2

Explanation / Answer

5)

we have:

Gof(NH4Cl(s)) = -203.9 KJ/mol

Gof(NH3(g)) = -16.7 KJ/mol

Gof(HCl(g)) = -95.27 KJ/mol

we have the Balanced chemical equation as:

NH4Cl(s) ---> NH3(g) + HCl(g)

deltaGo rxn = 1*Gof(NH3(g)) + 1*Gof(HCl(g)) - 1*Gof( NH4Cl(s))

deltaGo rxn = 1*Gof(NH3(g)) + 1*Gof(HCl(g)) - 1*Gof( NH4Cl(s))

deltaGo rxn = 1*(-16.7) + 1*(-95.27) - 1*(-203.9)

deltaGo rxn = 91.93 KJ/mol

Since deltaGo rxn is positive, the reaction is not spontaneous

Answer: doesn’t occur spontaneously
