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) | -20.6 | | | | 296.8 | | -241.8 |
| 205.8 | | 205. | | 248.2 | | 188.8 |
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 |
