Question

Passage of 96,500 coulomb of electricity liberates ________ L of O2 at 273°C and 2 atm during electrolysis.

Options

A.5.6
B.16.8
C.22.4
D.11.2

Solution

neq = n × n-factor = $\frac{Q}{F}$

Or, $\frac{1 \times V}{0.0821 \times 546} \times 4 = \frac{96500}{96500} \Rightarrow V = 5.6\text{ L}$
