Compare the energies of the bonds broken and those formed (see Table 9.5) for the reaction HCN(g)

Question:

Compare the energies of the bonds broken and those formed (see Table 9.5) for the reaction
HCN(g) + 2H2(g) → CH3NH2(g)
From this, conclude whether the reaction is exothermic or endothermic. What is the sign of ∆So? Explain. The reaction is spontaneous at 25oC. Explain this in terms of the enthalpy and entropy changes.
