Which of the following is the overall reaction of rusting?
(a) 2Fe(s) → 2Fe^2+ + 4e^–
(b) O2 (g)+4H^+(aq)+4e^–⟶2H2O(l)
(c) 2Fe(s) + O2(g) + 4H^+(aq) → 2Fe^2+(aq) + 2H2O(l)
(d) H2O ⇌ H^+ + OH^–
The question was asked in class test.
I would like to ask this question from Electrochemistry topic in portion Electrochemistry of Chemistry – Class 12
