How much current in columb is required to decrease 1 mol of `Cr_(2)O_(7)^(-2)` from the following reaction ?
`Cr_(2)O_(7)^(-2)+14H^(+) +6e^(-) to 2Cr^(+3)+7H_(2)O`

A

5,80,000 columb

B

5,79,500 columb

C

5,80,500 columb

D

5,79,000 columb

Text Solution

Verified by Experts

The correct Answer is:
D
`Cr_(2)O_(7)^(-2)+14H^(+)+6e^(-) to 2Cr^(+3)+7H_(2)O`
`6xx96500C=5,79,000` columb current is required.
