Question

Endothermic and Exothermic Activity

Answer 1

Answer:

Explanation:

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 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

Answer 2

Answer:

Explanation:

The interpretation of the Data Given in the question is  shown in the Table 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

SO; we need  to create the potential energy diagrams for each of the three chemical reactions. After that we are to analyze the data and your diagrams for each reaction.

SEE THE ATTACHED DIAGRAMS BELOW.

The attached diagrams carefully answers the every detailed information provided in the document.

Calculate the total change in enthalpy and the activation energy using the energy values provided for each reaction. Record those values below the graph.

the total  change in enthalpy and the activation energy are determined by Using the energy values provided for each reaction and they are recorded below the graph.

                                        Activation Energy        Enthalpy change

Synthesis reaction            45  kJ                           + 35  kJ

Single replacement          20   kJ                           - 35  kJ

reaction

Double replacement        65  kJ                             + 50  kJ

I hope that helps a lot!
