G^ v s l plot in the Eliingham's diagram, slopes downwards for the reaction

Options

  1. AMg + 1 2 O ₂ MgO
  2. B2 Ag + 1 2 O ₂ Ag ₂ O
  3. CC + 1 2 O ₂ CO
  4. DCO + 1 2 O ₂ CO ₂

Correct answer

C. C + 1 2 O ₂ CO

Step-by-step solution

For the reaction, C + 1 2 O ₂ CO , G^ vs T plot in the Ellingham's diagram slopes downwards. As for this reaction G^ become more negative with increase in temperature.
