Q: In a reaction at equilibrium, if the temperature is increased and the reaction is exothermic, what will happen? (2021)
Solution: For an exothermic reaction, increasing the temperature shifts the equilibrium to the left, favoring the reactants.
Steps: 5
Step 1: Understand what equilibrium means. It is a state where the forward and reverse reactions occur at the same rate.
Step 2: Identify that an exothermic reaction releases heat. This means heat is a product of the reaction.
Step 3: Recognize that increasing the temperature adds heat to the system.
Step 4: Apply Le Chatelier's Principle, which states that if a system at equilibrium is disturbed, it will shift to counteract the disturbance.
Step 5: Since we added heat (increased temperature) to an exothermic reaction, the system will try to reduce the heat by shifting the equilibrium to the left, favoring the reactants.
