Homework Statement
if you have an equation such as H2+2O2=2HNO2 and you know the partial pressure of H2 is .5 and the partial pressure of O2 is .3, does that mean that the partial pressure of 2HNO2 is .8?
Partial pressure is the pressure exerted by a single component of a mixture of gases. It is proportional to the number of molecules of that component in the mixture and to the absolute temperature.
Partial pressure can be calculated by multiplying the total pressure of the gas mixture by the mole fraction of the component in question. This gives the partial pressure of that component in the mixture.
Partial pressure is important because it helps determine how gases behave in a mixture. It also allows for the prediction of how gases will move or react in different conditions.
As altitude increases, the partial pressure of oxygen decreases due to the decrease in atmospheric pressure. This can lead to altitude sickness and difficulty breathing at high altitudes.
As temperature increases, the partial pressure of a gas increases due to the increase in kinetic energy of the gas molecules. This means that the gas molecules are moving faster and are exerting more pressure on their surroundings.
