C(s) + 2S(g) → CS\(_2\)(g)
ΔH = +89 kJ mol-1
The chemical equation above implies that
- each of carbon and sulphur has 89 kJ of energy
- both carbon and sulphur contribute 89 kJ of energy
- 89 kJ of energy is released
-
89 kJ of energy is absorbed
The correct answer is: D
Explanation
ΔH = + 89kJ means it is an endothermic reaction. However, endothermic reaction is one in which heat is absorbed into the system from the surrounding.
