Imagine a graph. The x-axis is labeled "Time" and is measured in seconds, and the y-axis is labeled "Potential Energy" and is measure in kilojoules (kJ). The slope starts at 0 seconds and a plateau at 25 kJ. This plateau is labeled "Reactants." The slop then rises to a peak labeled "Activation Energy" at 78kJ. Finally the slop drops to a plateau at 14kJ and is labeled "Products."
