In a typical fuel cell, the reactants (R) and product (P) are :-

In a typical fuel cell, the reactants (R) and product (P) are :-

Options

  1. AR=H2(g),O2(g);P=H2O2(ℓ)R = {H}_{2 ( g )}, {O}_{2 ( g )}; P = {H}_{2}{{O}_{2}}_{( ℓ )}
  2. BR=H2(g),O2(g);P=H2O(ℓ)R = {H}_{2 ( g )}, {O}_{2 ( g )}; P = {H}_{2}{O}_{( ℓ )}
  3. CR=H2(g),O2(g),Cl2(g);P=HClO4(aq)R = {H}_{2 ( g )}, {O}_{2 ( g )}, {Cl}_{2 ( g )}; P = {HClO}_{4 ( aq )}
  4. DR=H2(g),N2(g);P=NH3(aq)R = {H}_{2 ( g )}, {N}_{2 ( g )}; P = {NH}_{3 ( aq )}

Correct answer

B. R=H2(g),O2(g);P=H2O(ℓ)R = {H}_{2 ( g )}, {O}_{2 ( g )}; P = {H}_{2}{O}_{( ℓ )}

Step-by-step solution

In typical fuel cell
Reactants =H2,O2= {H}_{2}, {O}_{2}
Products =H2O= {H}_{2}O
