The oxidation of copper(I) oxide, Cu2O(s) , to copper(II) oxide, CuO(s) , is an exothermic process. 2Cu2O(s)+O2(g)⟶4CuO(s) The change in enthalpy upon reaction of 42.60 g Cu2O(s) is −43.47 kJ . Calculate the work, , and energy change, Δrxn , when 42.60 g Cu2O(s) is oxidized at a constant pressure of 1.00 bar and a constant temperature of 25∘ C . Note that ΔErxn is sometimes used as the symbol for energy change instead of Δrxn .
