When a 9.65 ampere current is passed for 1.0 hour into nitrobenzene in an acidic medium, what is the amount of p-aminophenol produced?

A. 109.0 g
B. 98.1 g
C. 9.81 g
D. 10.9 g

Answer :

Final answer:

The question involves applying Faraday's laws of electrolysis to calculate the amount of p-aminophenol produced from nitrobenzene when a specific current is applied for a set period of time.

Therefore, the correct answer of the given question is C.

Explanation:

The question asks for the amount of p-aminophenol produced when a current of 9.65 amperes is passed for 1.0 hour into nitrobenzene in an acidic medium. This is a problem involving Faraday's laws of electrolysis which relate electric charge to mole numbers during electrolysis reactions.

To find the amount of product formed, we need to calculate the moles of electrons transferred using the formula:

moles of electrons (n) = (current (I) in amperes × time (t) in seconds) / Faraday's constant (F)

Then, using the moles of electrons and the stoichiometry of the reaction, we can find the moles of p-aminophenol produced and convert that to grams using its molar mass.
