reaction between solid antimony(III) oxide and solid carbon?

Question

Question specifies at high temperatures also ... i believe its something like this :

Sb2O3(s) + C(s) --> _______ + _______
thanks for the help

Answer 1

Probably the carbon reduces the antimony III oxide to metallic antimony and produces carbon dioxide (similar to reaction for iron oxide).

2 Sb2O3 + 3 C >>>> 4 Sb(metal) + 3 CO2
