Be sure to answer all parts. use the following values of standard entropies and δs o rxn to determine the missing standard entropies. (a) k(s) → k(l) δs o rxn = 7.9 j/k · mols o (k(s)) = 63.6 j/k · mols o (k(l)) = ? j/k · mol (b) 2s(rhombic) + cl2(g) → s2cl2(g) δs o rxn = 44.74 j/k · mols o (s(rhombic)) = 31.88 j/k · mol s o (cl2(g)) = 223.0 j/k · mols o (s2cl2(g)) = ? j/k · mol (c) o2(g) + 2mgf2(s) → 2mgo(s) + 2f2(g) δs o rxn = 140.76 j/k · mols o (o2(g)) = 205.0 j/k · mol s o (f2(g)) = 203.34 j/k · mols o (mgo(s)) = 26.78 j/k · mols o (mgf2(s)) = ? enter your answer in the box provided. j/k · mol
