Question
Partial pressures of gas?
The picture below shows two bulbs connected by a stopcock. The 6.00-L bulb contains nitric oxide at a pressure of 0.850 atm, and the 1.50-L bulb contains oxygen at a pressure of 2.50 atm. which gases remain after the reaction goes to completion and calculate their partial pressures. I ne temperature at the beginnning and the end of the experiment is 22 degree C. Which gases are present at the end of the experiment? What are the partial pressures of the gases? If the gas was consumed completely, put 0 for the answer.Explanation / Answer
NO = 0.85 * 6 = 5.1
q2 = 1.5*2.5=3.75
oxygen is in excess as 3.75 x 2 = 7.5 of no is required to react. hence oxygen and no2 will remain at the end
amount of no2 formed is 5.1
oxygen remaining is ( 3.75 - (5.1/2 ) ) = 1.2
pno is zero as it is fully consumed,
p o2 is 1.2/(1.2 + 5.1) = 0.1904
and p no2 is 1-0.1904 = 0.809
gases present at end = O2 and NO2
Pno = 0
PO2 = 0.19
PNO2 = 0.809
