A mixture of 20 liters of hydrogen and nitrogen was passed over a catalyst to produce ammonia. After the reaction, the total volume decreased to 16 liters. Determine the volume of ammonia produced, assuming all volumes are measured at the same conditions.
- 4 liters
- 2 liters
- 8 liters
- 10 liters
📝 Detailed explanation
N₂ + 3H₂ ⇄ 2NH₃The decrease in volume is ΔV = (1 + 3) - 2 = 2 volumes for every 2 volumes of NH₃ produced.
Therefore, the decrease in volume equals the volume of NH₃ produced.
ΔV = 20 - 16 = 4 liters.
Volume of ammonia = 4 liters.
