When compared to G ^ for the formation of Al ₂ O ₃ , the G ^ for the formation of Cr ₂ O ₃ is

Options

  1. Ahigher
  2. Blower
  3. Csame
  4. Dunpredicted

Correct answer

A. higher

Step-by-step solution

Between Al ₂ O ₃ and Cr ₂ O ₃, Al ₂ O ₃ is more stable, so its ease of formation is high G^ is negative or less than that of Cr ₂ O ₃ . Hence, G ^ of Cr ₂ O ₃> G ^ of Al ₂ O ₃
