Question 64
Open questionMTNAT2 marksNeeds review
Al₂O₃ can be electrolyzed with an inert anode or a carbon anode.
Overall reactions are as follows:
Reaction I: For inert anode,
Reaction II: For carbon anode,
T denotes temperature in Kelvin
Given: Faraday constant = 96500 Coulomb
If inert anode is replaced by carbon anode during electrolysis of Al₂O₃ at temperature 1300 K, the decrease in the magnitude of decomposition potential between the two reactions (rounded off to two decimal places) is __________ Volts.
