Question

Find the volume of the gases evolved by passing 0.965a current for one hour

Answer 1

current , i = 0.965 A
time , t = 1hr = 3600 sec

we know, charge = current × time
= 0.965 × 3600 = 965 × 3.6 C

from Faraday's law,
1 mole of electrons be equivalent to 96500C

so, number of mole of gas evolved = 965 × 3.6/96500 = 3.6/100 = 0.036

now, use formula, number of moles = volume of gas/22.4L

so, volume of gas = number of moles × 22.4 L
= 0.036 × 22.4 L
= 0.8064L = 806.4 cm³
