NiNickel can be extracted from nickel sulfide concentrates at 1200 C via the following reaction:
(4NiO(s) + Ni_{3}S_{2}(s) -> 7Ni(s) + 2SO_{2}(g)
a) Calculate the mass feed rates of both NiO and Ni3S2 of 99.0% purity that are required to make 200 kg/hr of pure nickel.
b)Calculate the theoretical volume flow rate (Nm^3/hr) of sulfur dioxide gas that will form from this process.
