Question

At what temperature, zinc and carbon have equal affinity for oxygen?

• A. ${1000}^{\circ }C$
• B. ${1500}^{\circ }C$
• C. ${500}^{\circ }C$
• D. ${1200}^{\circ }C$

Answer 1

The correct option is A ${1000}^{\circ }C$

As both oxides met at ${1000}^{o}C$ in graph so at this temperature both C and Zn have equal affinity for oxygen.
