Question

Let's warm up our thinking with a generic reaction: Reactant 1 + Reactant 2 + heat ⇔ Product A Using the sample reaction, determine the shift that will result with each disturbance. (3 points) Favors Forward Reaction (Shift right) Favors Reverse Reaction (Shifts left) Removal of Reactant 2 Addition of heat Removal of Product A Question 2 The forward reaction seen here can be considered: Reactant 1 + Reactant 2 + heat ⇔ Product A (1 point) Responses Endothermic Endothermic Exothermic

Answer 1

To answer your first question regarding how the generic reaction will shift in response to different disturbances, let's analyze each scenario:

1. Removal of Reactant 2: This disturbance will shift the equilibrium to the left (favoring the reverse reaction) to replace the removed reactant.

   • Shift: Favors Reverse Reaction (Shifts left)

2. Addition of heat: Since heat is a reactant in this endothermic reaction, adding heat will drive the reaction towards the right (favoring the forward reaction) to use up the added heat.

   • Shift: Favors Forward Reaction (Shift right)

3. Removal of Product A: If Product A is removed, the equilibrium will shift to the right (favoring the forward reaction) to produce more product.

   • Shift: Favors Forward Reaction (Shift right)

Now, regarding Question 2, the given reaction can be classified based on its heat exchange. Since the reaction involves heat as a reactant and absorbs heat to form the products, it is considered endothermic.

• Response: Endothermic

Thus, the answer to Question 2 is Endothermic.
