Question 3
F

Which equation represents the overall reaction in a hydrogen fuel cell?

[1]
A

2H2+O2→2H2O2\text{H}_2 + \text{O}_2 \rightarrow 2\text{H}_2\text{O}2H2​+O2​→2H2​O

B

2H2O→2H2+O22\text{H}_2\text{O} \rightarrow 2\text{H}_2 + \text{O}_22H2​O→2H2​+O2​

C

H2+O2→H2O2\text{H}_2 + \text{O}_2 \rightarrow \text{H}_2\text{O}_2H2​+O2​→H2​O2​

D

2H2+2O2→2H2O22\text{H}_2 + 2\text{O}_2 \rightarrow 2\text{H}_2\text{O}_22H2​+2O2​→2H2​O2​
