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.

Answer 1

For the generic reaction provided:

Reactant 1 + Reactant 2 ⇔ Product A + Heat

let's analyze the shifts in response to various disturbances.

### Responses to Disturbances:

**Favors Forward Reaction (Shift right)**
**Favors Reverse Reaction (Shifts left)**

1. **Removal of Reactant 2**
- **Shift left** (Favors Reverse Reaction): When a reactant is removed, the system will shift to the left to replace the removed reactant.

2. **Addition of heat**
- **Shift left** (Favors Reverse Reaction): The reaction can be viewed as exothermic since heat is released as a product. Adding heat shifts the equilibrium to the left to absorb the excess heat.

3. **Removal of heat**
- **Shift right** (Favors Forward Reaction): By removing heat, the system will shift to the right to produce more heat, favoring the production of Product A.

4. **Addition of Reactant 1**
- **Shift right** (Favors Forward Reaction): Adding a reactant will drive the reaction to the right to use up the excess reactant and form more products.

5. **Removal of Product A**
- **Shift right** (Favors Forward Reaction): Removing a product will shift the equilibrium to the right to produce more of Product A.

### Question 2
For the question identifying whether the forward reaction is endothermic or exothermic:

The forward reaction is **Exothermic**.

This is because heat is produced (released) as a product of the reaction. Thus, the correct response is "Exothermic."
