In producing chlorine by electrolysis 100 kW power at 125 V is being consumed. How much chlorine per minute is liberated? (E.C.E. of chlorine is 0.367×10–3 kg / C)
-
- 1.76 × 10–3 kg
- 9.67 × 10–3 kg
- 17.61 × 10–3 kg
- 3.67 × 10–3 kg
Correct Option: C
| I = | P | = | 100 × 103 | A = | 105 | A |
| V | 125 | 60 |
E.C.E. = 0.367 × 10-6 kg C -1
Charge per minute = (I × 60) C
| = | C = | C | ||
| 125 | 125 |
∴Mass liberated
| = | 6 × 106 | × 0.367 × 10-6 |
| 125 |
| = | 6 × 1000 × 10-3 | = 17.616 × 10-3kg |
| 125 |
