WebA reaction coordinate is known as a collective variable in molecular dynamics simulations. A reaction coordinate diagram is a graph that shows the relationship between energy and reaction progress. The activation energy, which is the point on the graph where the line is curving up, is the amount of energy that needs to be added.
