Hi, there are 5 questions and I was wondering if you could check them for me. Thanks!
3. The hypothetical equilibrium reaction represented by the equation that follows.
QA(s) + 2 X(g)>>>Q(l) + X2A(g) + energy
This reaction can be shifted to increase the yield of products by adding.
My answer: This can be done by adding X’s to the reactant side; right side.
4. One step in the production of nitric acid is represented by the chemical equation that follows.
N2(g) + 2 O2(g) + 66.4 kJ>>>2 NO2(g)
List three ways that the amount of NO2(g) can be increased.
My answer: If the concentration were increased of the reaction
2nd: If the concentration of the products decreased
3rd: If the pressure increased
#5) Use the following information to answer the next \g questions.
I'm happy to help you check your answers! Let's go through each question one by one:
3. The hypothetical equilibrium reaction can be shifted to increase the yield of products by adding. Your answer, "This can be done by adding X’s to the reactant side; right side," is correct. To increase the yield of products, you would want to add more reactants in order to shift the equilibrium towards the products, according to Le Chatelier's principle.
4. In the production of nitric acid, the amount of NO2(g) can be increased in three ways. Your answers are partially correct. Here are the corrections:
- First, increasing the concentration of the reactants, N2(g) and O2(g), can drive the reaction forward and increase the yield of NO2(g).
- Secondly, decreasing the concentration of the products can also shift the equilibrium towards the products, increasing the amount of NO2(g).
- Finally, increasing the pressure would favor the side with fewer molecules, which in this case is the products. So, increasing the pressure would increase the yield of NO2(g).
