Question

Endothermic and Exothermic Activity For this assignment, you will create your own potential energy diagrams for each of the three chemical reactions. Then you will analyze the data and your diagrams for each reaction. 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 + BC AB + CD 10 kJ AD + BC 60 kJ 75 kJ. calculate the total change in enthalpy and the activation energy using the energy values provided for each reaction.

Answer 1

Answer:

Explanation:

The correct format 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 to create our own potential energy diagrams for each of the three chemical reactions.Then you will analyze the data and your diagrams for each reaction.

THE POTENTIAL ENERGY DIAGRAMS FOR THE THREE CHEMICAL REACTIONS  & THE ANALYSIS ARE SHOWN IN THE DIAGRAMS ATTACHED BELOW .

the total change in enthalpy and the activation energy using the energy values provided for each reaction is :

     

                                         Activation Energy        Enthalpy change

Synthesis reaction            45  kJ                           + 35  kJ

Single replacement          20   kJ                           - 35  kJ

reaction

Double replacement        65  kJ                             + 50  kJ
