Q
Q: Which of the following changes will increase the yield of products in an exothermic reaction at equilibrium?
Solution: Increasing the concentration of reactants will shift the equilibrium position to the right, favoring the formation of products.
Steps: 6
Step 1: Understand what an exothermic reaction is. It is a reaction that releases heat.
Step 2: Know what equilibrium means. It is the point where the rate of the forward reaction equals the rate of the reverse reaction.
Step 3: Learn about Le Chatelier's Principle. It states that if a change is made to a system at equilibrium, the system will adjust to counteract that change.
Step 4: Identify the change that can be made. In this case, we can increase the concentration of reactants.
Step 5: Realize that increasing the concentration of reactants will push the equilibrium to the right, meaning more products will be formed.
Step 6: Conclude that increasing the concentration of reactants will increase the yield of products in the exothermic reaction.
