Answer:
The correct answer is B
B . Is the enthalpy of formation of CS2 curve
Explanation:
The reaction is Endothermic (+89 kJ/mol) means it takes energy . It has to cross a potential -barrier.
Graph C can't be the answer (It is for exothermic reaction)
Graph A show that "total energy change is Zero" for the reaction .(because it is symmetrical). But it is 89 kJ/Mol , not zero
Hence, Graph B best describe the CS2 curve .
