Explanation:
Hello!
It is necessary to accommodate the reactions to get the reaction of my interest.
Reaction A reverses what modifies its energy in its sign (+72.6 KJ).
Reaction B doubles, which also doubles its energy (-514.4 KJ x 2).
Reaction C reverses what modifies its energy in its sign (-87.6 KJ).
By sum of the energies I get the energy of the global reaction.
