The thermodynamic properties of the higher manganese carbide in Mn7C3 have been determined by measuring the emf of the high-temperature galvanic cells
$$ ( - )M{n_{{solid}}}\left| {_{{MnC{l_2}}}^{{KCl = NaCl}}} \right|[M{n_7}{C_3} + {C_{{graphite}}}]( + ) $$
In the range 1000–1150°K the isobar-isothermal potential of the formation of the carbide is represented by the equation
$$ \Delta {Z^o} = - 22.470 - 0.492T\,kcal/mole $$
The standard heats and entropies of formation are, respectively, -19.8 ± 1.2 kcal/mole and 1.1 ± 0.4 cal/deg • mole.
