Answer 2

Answer: The volume of gases evolved at STP is 33.6 L

Explanation:

The half reactions for the electrolysis of $H_2SO_4$ follows:

Oxidation half reaction:  $H_2O\rightarrow 2H^++\frac{1}{2}O_2+2e^-$

Reduction half reaction:  $2H^++2e^-\rightarrow H_2$

The gases produced are hydrogen gas and oxygen gas

Moles of hydrogen gas = 1 mole

Moles of oxygen gas = 0.5 mole

When 2 Faradays of charge (2 electrons exchanged) is passed, the moles of gases produced are 1.5 moles

At STP:

1 mole of a gas occupies 22.4 L of volume

So, 1.5 moles of gas will occupy = $\frac{22.4}{1}\times 1.5=33.6L$ of volume

Hence, the volume of gases evolved at STP is 33.6 L
