Q
Q: For the exothermic reaction A + B ⇌ C + D, what effect does increasing the temperature have on the equilibrium? (2020)
Solution: For an exothermic reaction, increasing the temperature shifts the equilibrium to the left, favoring the reactants.
Steps: 6
Step 1: Understand that an exothermic reaction releases heat.
Step 2: Recognize that in the reaction A + B ⇌ C + D, the products (C and D) are formed from the reactants (A and B).
Step 3: Know that increasing the temperature adds heat to the system.
Step 4: Apply Le Chatelier's Principle, which states that if a change is made to a system at equilibrium, the system will adjust to counteract that change.
Step 5: Since the reaction is exothermic, adding heat will shift the equilibrium to the left, meaning it will favor the reactants (A and B).
Step 6: Conclude that increasing the temperature causes the equilibrium to shift towards the reactants.
