Studdy Solution
STEP 1
1. The reaction is exothermic, as indicated by .
2. We are considering the effect of temperature changes on the equilibrium position.
STEP 2
1. Understand the effect of temperature changes on exothermic reactions.
2. Classify the direction of the shift for each action.
STEP 3
In an exothermic reaction, heat is released, and the reaction can be considered to produce heat as a product.
STEP 4
Decreasing the temperature in an exothermic reaction removes heat, which shifts the equilibrium to the right to produce more heat.
STEP 5
Increasing the temperature in an exothermic reaction adds heat, which shifts the equilibrium to the left to absorb the excess heat.
Classification of actions:
- Decrease the temperature: Rightward shift
- Increase the temperature: Leftward shift
