Explanation:
Hello!
In this case, since the phosphoric acid is a triprotic acid, we infer it has three stepwise ionization reactions in which one hydrogen ion is released at each step, considering they are undergone due to the presence of water, thus, we proceed as follows:
Moreover, notice each step has a different acid dissociation constant, which are quantified in the following order:
Ka1 > Ka2 > Ka3
Best regards!
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
