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
Answer:
1. b. increase [NH3].
2. d. 0.01.
Explanation:
Hello!
In this case, for these equilibrium problems, we proceed as follows:
1. Here, we consider the Le C hatelier 's principle applied to a gas-phase reaction in which the reactants side have more number of moles; therefore, increasing the pressure will increase the products side as it has the fewest number of moles, so the answer is b. increase [NH3].
2. Here, we know that the equilibrium constant of the reverse reaction equals the inverse of the equilibrium constant of the forward reaction, thus, we obtain:
Therefore, the answer is d. 0.01.
Best regards!
