Question

At what approximate 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

Answer: (A)

${1000}^{\circ }C$

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