Examine the scenario.

aarav is studying a reversible reaction at chemical equilibrium in which the forward reaction is an exothermic reaction and the reverse reaction is an endothermic reaction. after making his initial observations, aarav cools the reaction, which removes thermal energy.

based on his knowledge of le châtelier's principle, what can aarav predict will occur?

the system will try to balance the change by shifting toward the endothermic reaction, and the rate of the reverse reaction will increase.
