The oxidation of copper(I) oxide, Cu_2O(s), to copper(II) oxide, CuO(s), is an exothermic process. 2Cu_2O(s) + O_2(g) rightarrow 4CuO(s) The change in enthalpy upon reaction of 63.82 g of Cu_2O(s) is -65.12 kJ. Calculate the work, w, and energy change, Delta U_rxn, when 63.82 g of Cu_2O(s) is oxidized at a constant pressure of 1.00 bar and a constant temperature of 25 degree C. w = Delta U_rxn = Note that Delta E_rxn is sometimes used as the symbol for energy change instead of Delta U_rxn
