what happens to the balance of a reversible reaction at equilibrium when temperature is increased?

the balance of the reaction shifts toward the side with more particles.

the balance of the reaction shifts toward the side with fewer particles.

the balance of the reaction shifts toward the endothermic reaction.

the balance of the reaction shifts toward the exothermic reaction.

The balance of the reaction shifts toward the endothermic reaction.

Explanation:

An ENDOTHERMIC REACTION requires input of HEAT ENERGY to drive it FORWARD from reactants, unto completion of products.

So, on increasing the temperature (available heat) the REVERSIBLE REACTION favors the shifts towards the endothermic reaction

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
