The following chart represents the energetics of a reaction. Identify whether the reaction is endothermic or exothermic, the activation energy of the uncatalyzed reaction, and the activation energy of the catalyzed reaction.Explanation / Answer
The Y-axis of the spectra represents the energy term.
If the energy of products -reactants is -ve quantity, then the reaction is exothermic. Here it is positive and thus endothermic
This is represented by the term d in the graph.
1.What type of question is this? These are the questions explaining the energy profile of a reaction.
Activation energy is the energy difference between the reactants and the transition state. (the energy difference between and highest energy point and that of the reactant). In the present case, it is represented as a
Kindly note that for a catalyzed reaction also, the energy of the reactants and the products are same. The only difference is the path and energy of transition state. in the graph, the dotted line represents catalyzed reaction.
The new activation energy is represented as e
