Question

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.

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

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.

Answer 1

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

Reason: heat is a reactant in the endothermic forward reaction, so removing heat drives the equilibrium toward the exothermic (reverse) direction to produce heat (Le Chatelier’s principle).
