Worked Solution & Example Answer:The change in energy during a reaction is represented in the following energy profile diagram - VCE - SSCE Chemistry - Question 3 - 2009 - Paper 1
Step 1
the activation energy for the reverse reaction.
Answer
In the context of an energy profile diagram, the change in energy denoted by ΔE refers to the energy difference between the reactants and the products. Specifically, this energy profile illustrates the activation energy barrier that must be overcome for the reaction to occur.
In this case, the activation energy for the reverse reaction corresponds to the energy required to convert the products back into the reactants. Thus, the correct answer is option C.
