A chemistry student needs to determine the enthalpy of desorption for a specific substance. The substance was adsorbed onto activated carbon in a packed bed reactor at 25°C and under a pressure of 4 bar. The adsorption process was carried out until saturation was reached. The packed bed reactor was then heated to 100°C until complete desorption. The pressure was maintained at 4 bar during the entire process. Given the initial mass of the adsorbate and the final mass of the activated carbon, calculate the enthalpy of desorption for the substance.

A chemistry student is conducting an experiment in a closed container where nitrogen dioxide is being converted into nitrogen oxide and oxygen gas. If the student increases the concentration of the nitrogen dioxide in the container, how will it affect the equilibrium position of the reaction and what can be done to restore the equilibrium position? Use Le Chatelier's principle to explain your answer.
