What is number of moles of electron passed when a current of 2 Amp flows through solution of electrolyte for 10 minutes?

Options

  1. A1.784 10⁻²
  2. B1.243 10⁻²
  3. C2.022 10⁻²
  4. D8.041 10⁻²

Correct answer

B. 1.243 10⁻²

Step-by-step solution

Given, current I = 2 A and time t = 10 minutes = 10 60 = 600 s. Total charge passed is given by Q = I t Q = 2 600 = 1200 C The charge of one mole of electrons is 1 Faraday ( F 96500 C). Number of moles of electrons = Q F Number of moles of electrons = 1200 96500 = 0.012435 mol Number of moles of electrons 1.243 10⁻² mol Answer: 1.243 10⁻²
