In aCu-voltameter, mass deposited in30 sis 'm' g. If the time-current graph is shown in the following figure:



What is the electrochemical equivalent ofCu?

Options:

Answer:
B
Solution:

Total current passed in 30 sec = Area of current-time curve

=( 1 2 ×100×10 )+( 100×10 )+( 100×10 )+( 1 2 ×100×10 )

= 3 × 100 × 10 mA × s

= 3000 × 103 amp s=3 C

W=EQForWQ= EF=Z=m3
