heat will be absorbed and the products will be formed faster exothermic reaction will undergo spontaneously as it does not require any energy while endothermic reaction has to be supplied with energy to happen therefore exothermic reaction will be faster than endothermic reaction
Classify this reaction as endothermic or exothermic. 5. Consider the reaction A + 2B â C. In this reaction, the total energy of the reactants is 80 kJ mol-1, the total energy of the products is -90. kj mol-1 and the activation energy for the forward reaction is 120 kj mol-1. a. Draw a diagram of the energy profile for this reaction. Label the diagram. B State whether the reaction is endothermic or exothermic.
