Question

The volume of gases evolved at STP by passing $0.2$A of current for $964$s through an aqueous solution of sodium fumarate is:

Answer 1

$CH-COONa$

$||$

$CH-COONa$ {Sodium fumarate}

$2F=2\times 96500C\Rightarrow 4\times 22.44t$

$\Rightarrow 0.2\times 964⟶\frac{4\times 22.4\times 0.2\times 964}{2\times 96500}$

$=0.0896lit$

$=89.6ml$ .
