Answer:

D. Exothermic

Explanation:

The enthalpy, ΔH, of a reaction is defined as the change in heat when a reaction occurs.

A reaction with ΔH > 0 is called endothermic and requires energy to be produced

A reaction with ΔH < 0 is called exothermic and produce energy when occurs (An example is the combustion of octane that produce energy that is used in engines to produce movement)

As the enthalpy of the reaction is -1207kJ/mol (ΔH < 0) the reaction is:

D. Exothermic
