How would the equilibrium of an exothermic reaction at 25°c be affected if the temperature of the system were reduced? (hint: apply le chatelier's principle)?

-

Equilibrium shifts towards the reactants.

Explanation:-

An exothermic reaction means energy is released. Since energy gets released the temperature increases.

A --> B + temperature increase due to energy release

For an exothermic reaction, thus temperature increase is like a product of the reaction.

Now if the temperature of the system is reduced, then as per le chatelier priniple the equilibrium shifts towards the reactants.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
