Please see the attached picture for the explanation.

Le Châtelier's principle:

When a stress is applied to a system at equilibrium, the system will respond by shifting in the direction that opposes/ minimizes the effect of the stress.

• This stress could be the addition or removal of a product or reactant, changes in the concentration of the products or reactants, or a change in temperature.

☆ Why can heat be written on the same side of the products when the reaction is exothermic?

• Exothermic means that heat is released, thus heat can be treated as a product.

• I like to remember it as Exothermic → Exit

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
