During the electrolysis of molten sodium chloride, the time required to produce

0 . 10mol

of chlorine gas using a current of

3amperes

is

Options

A $55minutes$
B $110minutes$
C $220minutes$
D $330minutes$

Correct answer

B. $110minutes$

Step-by-step solution

For

1mole

of

C{l}_{2}, 2F

electricity is required.

∴

For

0 . 1mole

of

C{l}_{2}, 0.2F

electricity will be required.

∴ Q = I \times t

or,

t = \dfrac{Q}{I} = \dfrac{0.2 \times 96500}{3 \times 60} \approx 110

minutes.
