Question

Out of coke and CO which is better reducing
agent for the reduction of ZnO?why?

Answer 1

Coke is definitely the better reducing agent for the reduction of zinc oxide (ZnO) than carbon monoxide (CO). The Gibbs free energy of formation becomes lower at temperatures above 1273 K, for CO2 from C. In case of CO2 from CO, the Gibbs free energy of formation is always higher than ZnO.
