Question

a) Read the graphs is energy absorbed or release as a reaction progresses from the reactants to the activation complex?b) compare how are the graphs for the reactions 1 and 2 different?

Answer 1

A) The graph that shows energy changes in reaction 2 is showing an endothermic reaction. This graph shows that the reaction is absorbing energy. On the other hand, the graph that shows the energy changes in reaction 1 is showing an exothermic reaction meaning energy is being released.

B) The graph for reaction 2 shows that the reactants are lower than the products whilst on reaction 1 the reactants are higher than the products. For reaction 2 the activation energy is greater than that of reaction 1.
