Elementary reaction graph
WebConsider the reversible gas phase elementary reaction. The rate law for this gas phase reaction will follow an elementary rate law. Where Kcis the concentration equilibrium constant. We know from Le Chaltlier's Law that if the reaction is exothermic, Kcwill decrease as the temperature is increased and the reaction will be shifted back to the left. WebAug 13, 2016 · Explanation: The rate determining step in a reaction mechanism is the slowest step. It is characterized by its high activation energy. Consider the energy diagram represented below of a two-step mechanism. The first step is the slow step since it has the highest activation energy. Here is more about this topic in the following video:

WebHelpful Steps to Create an Energy Diagram. 1) Label the axes. The x-axis is labeled as the reaction coordinate, and the y-axis is labeled as energy. 2) Draw a line at the beginning of the graph for the reactants and a line at the end for the products. The products will be higher or lower depending on if the reaction is endothermic or exothermic ... WebReaction Chegg.com. 14.70 Consider the following energy profile.
