112. With the help of standard enthalpies of education and standard entropy at 25 ° C (Table 11.4. Appendix II), calculate the standard values of enthalpy, internal energy, energy of Gibbs and the energy of the Helmholtz reaction below, at the same temperature. Determine in which direction the reaction will go, in the direct or reverse.
The task is reaction
112 s (t) n2o (d) = C (d) H2 (d)
