40. Solving a chemistry problem

6. Using the reference data, determine H298, S298, G298 given in the reaction tasks; draw a conclusion regarding the spontaneous flow of the process at T = 298 K, for reversible processes, determine the equilibrium conditions. For the molecule given under the letter e), determine the atomic enthalpy of formation and the average binding energy in the molecule.
a) 2CH4 (g) = C2H6 (g) H2 (g)
b) C2H6 (d) = 2C (c, graph) 3H2 (d)
c) C(k, graph) = C(g)
d) H2 (g) = 2H (g)
e) PCl3
