Consider an endothermic reaction such as the generic one seen here:

Reactant 1 + heat ⇔ Product A + Product B

Determine what results if an industrial chemist removes heat from the system.

Product A will form Reactant 1 in a reverse reaction as Product B is left behind at lower temperatures
Product A will form Reactant 1 in a reverse reaction as Product B is left behind at lower temperatures

The reaction shifts left as the products reform the original reactant at lower temperatures.
The reaction shifts left as the products reform the original reactant at lower temperatures.

The reaction will remain in dynamic equilibrium with no net change at higher temperatures.
The reaction will remain in dynamic equilibrium with no net change at higher temperatures.

The reaction shifts right since there will be more products formed at higher temperatures.

In an endothermic reaction, heat is a reactant, meaning it is absorbed for the reaction to proceed towards the products. According to Le Chatelier's principle, if heat is removed from the system, the equilibrium will shift in the direction that produces heat to counteract the change—in this case, it will shift towards the left to favor the formation of the reactants.

Therefore, the correct response is:

The reaction shifts left as the products reform the original reactant at lower temperatures.
