Question

Let's warm up our thinking with a generic reaction: Reactant 1 + Reactant 2 ⇔ Product A + Heat Using the sample reaction, determine the shift that will result with each disturbance. (5 points) Favors Forward Reaction (Shift right) Favors Reverse Reaction (Shifts left) Removal of Product A Addition of heat Addition of Reactant 1 Removal of Reactant 2 Removal of heat Question 2 The forward reaction seen here can be considered: Reactant 1 + Reactant 2 ⇔ Product A + Heat (1 point) Responses Endothermic Endothermic Exothermic

Answer 1

Let's analyze the given reaction and what happens under different disturbances:

Reaction:
Reactant 1 + Reactant 2 ⇔ Product A + Heat

1. Removal of Product A:
   This disturbance will shift the equilibrium to the right (forward reaction) to replace the removed Product A.
   Shift: Favors Forward Reaction (Shift right)

2. Addition of heat:
   Since heat is a product in this reaction, adding heat will shift the equilibrium to the left (reverse reaction) to absorb the excess heat.
   Shift: Favors Reverse Reaction (Shifts left)

3. Addition of Reactant 1:
   Adding more Reactant 1 will shift the equilibrium to the right (forward reaction) to use up the added reactant.
   Shift: Favors Forward Reaction (Shift right)

4. Removal of Reactant 2:
   Removing Reactant 2 will shift the equilibrium to the left (reverse reaction) because there are fewer reactants available to form Product A.
   Shift: Favors Reverse Reaction (Shifts left)

5. Removal of heat:
   Since heat is a product, removing heat will shift the equilibrium to the right (forward reaction) to produce more heat.
   Shift: Favors Forward Reaction (Shift right)

Question 2: The forward reaction can be considered:
Since heat is released as a product when Reactant 1 and Reactant 2 react to form Product A, this indicates that the reaction is exothermic.
Response: Exothermic
