A 5 L container is held at a constant temperature. Initially it has a partial pressure of 1.2 bar N₂ and a partial pressure of 0.3 bars H₂. The nitrogen and hydrogen react to form some NH₃ and the total pressure is found to be 1.425 bar. What is the partial pressure of NH₃?

Question

Quizplus · Accepted Answer

The initial total pressure is 1.5 bar (1.2 + 0.3). After reaction, the total pressure is 1.425 bar. The decrease in pressure (0.075 bar) is due to the formation of NH₃. Thus, the partial pressure of NH₃ is 0.075 bar.
