Ответ:
kindly, find the attached images.
Part 1: image 1.
Part 2: image 2.
Explanation:
Part 1: Describe how you can determine the total change in enthalpy and activation energy from the diagram, and if each is positive or negative.
Kindly find image 1.
The total change in enthalpy (ΔH) is the difference in potential energy between products and reactants. (P.E. of products > P.E. of reactants).ΔH = (P.E.) products - (P.E.) reactants.
So, it will be positive.
Activation energy is the difference between potential energy of the intermediate and reactants.It will be positive.
Part 2: Describe how the curve will look if the reaction was exothermic. Be sure to mention changes in the potential energies of the reactants and products and the sign changes of the enthalpy.
Kindly find image 2.
The total change in enthalpy (ΔH) is the difference in potential energy between products and reactants. (P.E. of products < P.E. of reactants).ΔH = (P.E.) products - (P.E.) reactants.
So, it will be neagtive.
Activation energy is the difference between potential energy of the intermediate and reactants.It will be positive.
