Question

If the equilibrium system were stored in a vessel (with no heat transfer into or out of the vessel from the surroundings), predict what would happen to the temperature reading on a thermometer placed in the solution when hydrochloric acid is added. explain.

Answer 1

The system will experience a reaction with adding of the element hydrochloric acid (HCl). The equilibrium is shifted and the potential energy, where it will be absorbed by the energetic component of the product as sch the overall temperature reading will also decrease as the heat due to potential energy is absorbed and/or contained.
