What is the overall reaction in the fuel cell when hydrogen reacts with oxygen?

Options

  1. A2H 2 (g) + O 2 (g) → 2H 2 O(l )
  2. BO 2 (g) + 2H 2 O(l) + 4e-→ 4OH-(aq)
  3. C2H 2 (g) + 4OH-(aq) → 4H 2 O(l) + 4e-
  4. D2H 2 O(l) + O 2 (g) → 2H 2 (g) + 4OH-(aq)

Correct answer

A. 2H 2 (g) + O 2 (g) → 2H 2 O(l )

Step-by-step solution

The overall reaction in the fuel cell when hydrogen reacts with oxygen "2H 2 (g) + O 2 (g) → 2H 2 O(l )"
