विकल्प

• 12 × 10⁴⁶

• 96500

• 6.022 × 10²³

• 8 × 10¹⁶

Answer 1

Number of electrons involved in the reaction, when 1 Faraday of electricity is passed through an electrolytic solution is 6.022 × 10²³.

Explanation:

Given,

Quantity of charge passed (Q) = 1 F

= 1 × 96500 C = 96500 C

Value of electron charge (e^-) = 1.60217 x 10-¹⁹ C

We know that, Q = ne^- 

⇒ n = `"Q"/"e"^- = (96500 "C")/(1.60214 xx 10^-19 "C")` = 6.022 × 10²³
