Why Zinc oxide can be reduced to the metal by heating with Carbon andnot with Cr_2O_3 ?

In Goldschmidt reaction, certain metallic oxides are reduced to the metallic by oxides are reduced to the metallic state by heating with:

The oxide of a metal (R ) can be reduced by the metal (P) and metal (R ) can reduce the oxide of metal (Q). Then the decreasing order of the reactivity of metal (P), (Q) and (R ) with oxygen is :

The oxide of a metal (R ) can be reduced by the metal (P) and metal (R ) can reduce the oxide of metal (Q). Then the decreasing order of the reactivity of metal (P), (Q) and (R ) with oxygen is :
