WebWe would like to show you a description here but the site won’t allow us. WebSuppose that the reaction A¡products is exothermic and has an activation barrier of 75 kJ>mol. Sketch an energy diagram showing the energy of the reaction as a function of … WebCollision theory says that particles must collide in the proper orientation and with enough kinetic energy to overcome the activation energy barrier. So let's look at the reaction where A reacts with B and C to form AB plus C. On an energy profile, we have the reactants over here in the left.
