Calculate the enthalpy of desorption of CO2 from sodium hydroxide (NaOH) pellets given the following information: - The heat of absorption of CO2 by NaOH pellets is -20.9 kJ/mol.- The standard enthalpy of formation of Na2CO3 is -1130 kJ/mol.- The standard enthalpy of formation of water is -286 kJ/mol.- The standard enthalpy of formation of NaOH is -425 kJ/mol. Assuming that the desorption process is the reverse of the absorption process, determine the enthalpy change for the reaction: Na2CO3(s) + H2O(l) → 2NaOH(s) + CO2(g).
