Options
- A. 1.784 10^ -2
- B. 1.243 10^ -2
- C. 2.022 10^ -2
- D. 8.041 10^ -2
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
