Which of the following changes is most likely to decrease reaction rate for the chemical reaction 2CO + O₂ $\rightarrow$2CO₂?

Question

Quizplus · Accepted Answer

According to Le Chatelier's principle, removing one of the reactants (CO in this case) will shift the equilibrium towards the reactants, resulting in a decrease in reaction rate. Therefore, removing some CO from the reaction mixture is most likely to decrease the reaction rate. Option A would increase the concentration of one of the reactants and is likely to increase the reaction rate. Option B would increase the temperature and is likely to increase the reaction rate. Option C is likely to increase the reaction rate by providing an alternative pathway with a lower activation energy.
