Potential Energy as a Function of Internuclear Distance
Explain the reason for the potential energy level at each labeled point on the graph. The bond energy of H2 is. Worked Example Interpreting Potential Energy Curves Of Diatomic Molecules Khan Academy Youtube The graph shows the potential energy as a function of internuclear distance for molecular chlorine CI - CI and an unknown homonuclear diatomic molecule A - A. . In our case we can set x as r 2 so we should get a quadratic potential energy like shown in the grey dotted line in the figure. A graph of potential energy versus internuclear distance for two Cl atoms is given below. 1682 students attemted this question. ItexE frac12kx2itex Now look at this equation. The original is taken to be 0 0. The relation has the form V De1expnΔr22r1afr where the parameter n is defined by the equation n kereDe. Horizontal lines represent vibrational energy levels.
