The standard cell potential of $Zn|Zn^{2+}_{(aq)}||Cu^{2+}_{(aq)}|Cu$ cell is $1.10 \, V$. The maximum work obtained by this cell will be ............. $kJ$.

$A$ device that converts the energy of combustion of fuels like hydrogen and methane directly into electrical energy is known as:

$A$ fuel cell uses $CH_4$ gas and it forms $CO_3^{2-}$ at the anode. It is used to power a car with $96.5 \ A$ for $10000 \ s$. The volume of $CH_4$ gas required at $1 \ atm$ and $273 \ K$ is $............ \ L$.

Consider the Galvanic cell $Zn|ZnSO_4||CuSO_4|Cu$. The reaction at the cathode is

Given that
$E^o_{Ni^{2+} | Ni} = -0.25 \ V$
$E^o_{Cu^{2+} | Cu} = 0.34 \ V$
