Which of these is the strongest oxidizing agent listed here?

Question

Consider the following half-reactions. Which of these is the strongest oxidizing agent listed here?

Au⁺(aq) + e^- → Au(s) E^o = 1.69 V

N₂O(g) + 2 H⁺(aq) + 2 e^- → N₂(g) + H₂O(l) E^o = 1.77 V

Cr³⁺(aq) + 3 e^- → Cr(s) E^o = -0.74 V

The answer is: N₂O

please show steps so I can follow, thank you!

Answer 1

I don't know that there are any "steps". You just look for the reaction that has the greatest reduction potential. That will be the one that is most easily reduced, making it the better oxidizing agent. Hope that makes sense.
