Question

Endothermic and Exothermic Activity

Answer 1

Answer:

Explanation:

The perfect illustration for the  Table is shown below:

Generic Reactions           Reactants              Products              Transition state

Synthesis

A + B → AB                 A+B = -15 kJ           AB     = 20 kJ                  30 kJ

Single

Replacement

C + AB → CB + A       C + AB = 65 kJ         CB + A  = 30 kJ              85 kJ

Double

Replacement

AB+CD → AD+CB      AB+CD   = 10 kJ       AD+CB   =  60 kJ            70 kJ

We are tasked to create the potential energy diagrams for each of the three chemical reactions.Then, analyze the data and your diagrams for each reaction.

TO ANSWER THAT ; I HAVE CAREFULLY DRAWN THE POTENTIAL ENERGY DIAGRAMS FOR THE THREE CHEMICAL REACTIONS  & THE ANALYSIS FOR EACH ARE SHOWN IN THE DIAGRAMS ATTACHED BELOW .

NOW; over to the total  change in enthalpy and the activation energy: Using the energy values provided for each reaction is : we can see the calculation of the  total change in enthalpy and the activation energy in the diagram as well by using the energy values provided for each reaction.

                                        Activation Energy        Enthalpy change

Synthesis reaction            45  kJ                           + 35  kJ

Single replacement          20   kJ                           - 35  kJ

reaction

Double replacement        65  kJ                             + 50  kJ
