Chemistry

Please show all work

A.)Place the following in order of decreasing standard molarentropy.

NaCl(s) Na3PO4(aq) NaCl(aq)

a.NaCl(aq) > Na3PO4(aq) >NaCl(s)
b.NaCl(aq) > NaCl(s) >Na3PO4(aq)
c.Na3PO4(aq) > NaCl(aq) >NaCl(s)
d.NaCl(s) > NaCl(aq) >Na3PO4(aq)
e.NaCl(s) > Na3PO4(aq) >NaCl(aq)

B.)Calculate the ΔG°rxn using the followinginformation.

2 H2S(g)+3 O2(g)→2 SO2(g)+2 H2O(g)
ΔH°f(kJ/mol)-20.6296.8-241.8
S°(J/mol∙K)
205.8205.248.2188.8

ΔG°rxn = ?

a.+108.2 kJ
b.+196.8 kJ
c.-147.1 kJ
d.+676.2 kJ
e.-466.1 kJ

C.)Calculate the ΔG∘rxn for the reaction using the followinginformation.

4HNO3(g)+5N2H4(l)→7N2(g)+12H2O(l)

ΔG∘f(HNO3(g)) = -73.5 kJ/mol;
ΔG∘f(N2H4(l)) = 149.3 kJ/mol;
ΔG∘f(N2(g)) = 0 kJ/mol;
ΔG∘f(H2O(l)) = -273.1 kJ/mol.

a.+110.7 kJ
b.-3.298 x 103 kJ
c.-954.7 kJ
d.+2.845 x 103 kJ
e.-312.9 kJ
