Question

Find the energy in kJ per mole of electronic charge accelerated by a potential of 2 volts.

[Write your answer close to the nearest integer]

Answer 1

By formula,

Energy in kJ$=$charge in Columb$\times$ P.D in volts

$=1.6\times {10}^{-19}\times 6.02\times {10}^{23}\times 2$

$=192.64\approx 193$ kJ/mole

Thus energy in KJ per mole uses electronic charge is accelerated by a potential of 2V is 193 kJ/mole.
