Question

(a)explain the extraction of zinc with chemical reactions out of c and co, which is a better reducing agent for zno and why. why is zinc not extracted from zinc oxide through reduction using co?

Answer 1

The standard Gibbs free energy of formation of ZnO from Zn is lower than that of CO2 from CO. Therefore, CO cannot reduce ZnO to Zn. Hence, Zn is not extracted from ZnO through reduction using CO.
