Nitrogen monoxide reacts with oxygen to give nitrogen dioxide: 2 NO(g) + O 2 (g) → 2 NO 2 (g) (a) Place the three gases in order of increasing rms speed at 298 K. (b) If you mix NO and O 2 in the correct stoichiometric ratio and NO has a partial pressure of 150 mm Hg, what is the partial pressure of O 2 ? (c) After reaction between NO and O 2 is complete; what is the pressure of NO 2 if the NO originally had a pressure of 150 mm Hg and O 2 was added in the correct stoichiometric amount?

Expert Solution
Interpretation Introduction
Interpretation:
The given gases reaction should be arranged in the order of increasing rms speed at given temperature and (O2) and (NO2) partial pressure should calculate and identified.
Concept introduction:
The root mean square velocity μ is defined as the measure of velocity of particle in gas. It is the method to determine the single velocity value for particles.
Root mean square velocity can be determined,
μrms=(3RTM)1/2 (1)
(gas constant)R=8.314JKmolM=Molarmass
Molar mass: The molar mass of a substance is determined by dividing the given mass of substance by the amount of the substance.
Partial pressure: The mixture of gases each gas has a partial pressure which is the hypothetical pressure of that gas if it alone occupied the entire volume of the original mixture at the same temperature.
Answer to Problem 89GQ
The increasing order of rms speed for given set of gases at given temperature is as follows, NO2 < O2 < NO
Explanation of Solution
