The choice of a reducing agent in a particular case depends on thermodynamic factors. How far do you agree with this statement? Support your opinion with two examples.

Out of $C$ and $CO$,which is a better reducing agent at $673 \, K$?

What is the substance added during the extraction of metals that combines with impurities to form a molten product called?

Consider the following reactions at $1000\,^{\circ}C$:
$(I)$ $Zn_{(s)} + 1/2 O_{2(g)} \xrightarrow{\Delta} ZnO_{(s)};$ $\Delta G^o = -360\,kJ\,mol^{-1}$
$(II)$ $C_{(s)} + 1/2 O_{2(g)} \xrightarrow{\Delta} CO_{(g)};$ $\Delta G^o = -460\,kJ\,mol^{-1}$
Choose the correct statement at $1000\,^{\circ}C$.
