At 1024 C, the pressure ox oxygen gas from the decomposition of copper(II) oxide (CuO) is 0.49 bar: 4CuO(s) --> 2Cu2O(s) + O2(g). (a) Calculate the fraction of CuO that will decompose if 0.16 mole of it is placed in a 2.0 L flask at 1024 C. (b) What would the fraction be if a 1.0 mole sample of CuO were used? (c) What is the smallest amount of CuO (in moles) that would establish the equilibrium?
