MCQ
In a typical fuel cell, the reactant ($R$) and product ($P$) are
  • A
    $R=H_{2(g)} \cdot N_{2(g)}: P=N H_{3(a q)}$
  • B
    $R=H_{2(g)} \cdot O_{2(g)}: P=H_{2} O_{2(n)}$
  • $R=H_{2(g)} \cdot O_{2(g)}: P=H_{2} O_{(n}$
  • D
    $R=H_{2(g)} \cdot O_{2(g)} \cdot C I_{2(g)}: P=H C I O_{4( aq )}$

Answer

Correct option: C.
$R=H_{2(g)} \cdot O_{2(g)}: P=H_{2} O_{(n}$
c
Cell reaction involved in hydrogen-oxygen fuel cell is

$2 H _{2}( g )+ O _{2}( g ) \longrightarrow 2 H _{2} O (\ell)$
