The standard enthalpy change of a reaction is positive thus endothermic.
The standard enthalpy change of a reaction is negative thus exothermic.
Hope it helped!
If the graph shows that the energy increases as the reaction proceeds, this means that the state of the reaction of the compounds A, B, C and D is exothermic because the system releases heat to the surroundings, thus, resulting to the increase in energy involved in the reaction.
