The diagram below shows the potential energy changes for a reaction pathway. Part 1: Does the diagram illustrate an enothermic or an exothermic reaction? Give reasons to support your answer.

Part 2: Describe how you can determine the total change in ethalpy and activation energy from the diagram and if each is positive or negative.

Brainliest if you give the definition of endo and exothermic reactions, and how you know the change in enthalpy even if you put nothing else.​

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
