Question
To help you understand how to interpret potential energy diagrams. The graphs shown here are called potential energy diagrams. They show the potential energy of a system as it changes from reactants to products. The first graph shows the uncatalyzed reaction (Figure 1); the second graph shows the catalyzed reaction (Figure 2). What is the value of the activation energy of the uncatalyzed reaction? Express your answer to three significant figures and include the appropriate units. What is the value of the enthalpy change of the uncatalyzed reaction? Express your answer to three significant figures and include the appropriate units. What is the value of the activation energy of the uncatalyzed reaction in reverse? Express your answer as an integer and include the appropriate units.Explanation / Answer
partA) from the potential digrams
the activation energy = 400 - 225 = 175 Kj
partb)
the enthalphy change = 225-100 = 125Kj
part C)
the activation energy for the reverse reaction = 400 - 100 = 300 Kj
