Derivative of potential energy
WebPotential Energy Derivation Potential energy is the work done to take a body to a certain height. For a body with mass m, h is the distance to which it is raised and g is the … WebFigure 30.10. 9: This graph shows the potential energy relationships for the reaction F + D 2 DF + D. The activation energy for the forward reaction is about 6 kJ/mol. The difference in potential energy between the reactants and the products is D e ( D 2) − D e ( DF). The curve’s peak represents the transition state.
