| 英文摘要 | molar enthalpies of dissolution of {znso4 center dot 7h(2)o(s) + l-aa(s)} (in which aa are valine, methionine, histidine and threonine, respectively) in 100 cm(3) of 2 mol . dm(-3) hcl at t= (298.15 +/- 0.001) k have been measured to be, delta h-d(m,l)o = (94.588 +/- 0.025) kj . mol(-1), (-70.619 +/- 0.051) kj . mol(-1), -(13.129 +/- 0.013) kj . mol(-1), and (72.001 +/- 1.602) kj . mol(-1), respectively, by means of an isoperibol solution-reaction calorimeter. molar enthalpies of dissolution of zn(aa)so4 center dot h2o(s) in 100 cm(3) of 2 mol . dm(-3) hcl at t= (298.15 +/- 0.001) k have been determined to be delta h-d(m,2)o = -(46.118 +/- 0.055) kj.mol(-1),(58.415 +/- 0.046)kj.mol(-1), -(11.271 +/- 0.012) kj . mol(-1), and (6.9 +/- 0.8) kj . mol(-1), respectively, by the calorimeter. the standard molar enthalpies of formation of the complexes zn(aa)so4 center dot h2o(s) have been derived to be, delta h-f(m)o [zn(val)so4 center dot h2o, s, 298.15 k] = -(1850.97 +/- 1.92) kj . mol(-1), delta h-f(m)o [zn(met)so4 center dot - h2o, s, 298.15 k] = -(2069.304 +/- 0.743) kj . mol(-1), delta h-f(m)o [zn(his)so4 center dot h2o, s, 298.15 k] -(1827.61 +/- 2.31) kj . mol(-1) and delta h-f(m)o[zn(thr)so4 center dot h2o, s, 298.15 k] -(2111.9 +/- 3.40) kj . mol(-1), by the combination of the experimental values of enthalpies of dissolution with some auxiliary thermodynamic data through a designed hess thermochemical cycle on the basis of a supposed chemical reaction.
