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 heat


Removal of Reactant 2


Removal of Product A


Addition of heat


Addition of Reactant 1


Question 2
The forward reaction seen here can be considered:

Reactant 1 + Reactant 2 ⇔ Product A + Heat

Answer 1

Reaction: Reactant 1 + Reactant 2 ⇔ Product A + Heat (heat is a product → forward reaction is exothermic)

Disturbance and shift (Le Chatelier’s principle):

- Removal of heat → Shift right (favors forward) — system produces heat.
- Removal of Reactant 2 → Shift left (favors reverse) — system makes more Reactant 2.
- Removal of Product A → Shift right (favors forward) — system makes more Product A.
- Addition of heat → Shift left (favors reverse) — system consumes added heat.
- Addition of Reactant 1 → Shift right (favors forward) — system consumes added reactant.

Question 2 answer: Exothermic.
