However she got it wrong. What is her error and what should the answer have been? Anna's statement: The equation is an exothermic reaction because the energy is released from liquid CO2 to the surroundings to become gaseous CO2 causing the molecules to slow down.Question contains sub-parts: Le Chatelier’s Principle states that when a system is at equilibrium it is subjected to stress, the system will shift its equilibrium point in order to relieve the stress.
