Consider the reaction `:`
`Cr_(2)O_(7)^(2-)+14H^(o+)+6e^(-) rarr 2Cr^(+3)+8H_(2)O`
What is the quantity of electricity in coulombs needed to reduce `1 mol e` of `Cr_(2)O_(7)^(2-)` ?

Text Solution

Verified by Experts

From the reaction,1 mol of `Cr_(2)O_(7)^(2-)` require 6 F
`=6xx96500=579000C`
`therefore579000C` of electrcity are required for reduction of `Cr_(2)O_(7)^(2-)` to `Cr^(3+)`.
