For the formation of which compound in Ellingham diagram G^ becomes more and more negative with increase in temperature?

Options

  1. ACO
  2. BFeO
  3. CZno
  4. DCu ₂ O

Correct answer

A. CO

Step-by-step solution

For formation of carbon monoxide ( CO ), the Ellingham diagram shows that the G^ becomes negative with an increase in temperature. It indicates that the formation of CO from carbon (C) and oxygen ( O ₂ ) becomes more favourable at higher temperatures.
