Concept explainers
(a)
Interpretation:
Temperature of each curve of distribution of speeds for
Concept Introduction:
Maxwell distribution curve shows the different fraction of gas molecules moves with different speeds. It also shows that heavy molecules have slow speed while lighter molecules have faster speeds. The formula to calculate faction of gas molecules with given speed
(b)
Interpretation:
Value of
Concept Introduction:
Root mean square speed is square root of average value of square of molecular speeds of molecules of gas. It includes molecular weight and temperature, both of which affect kinetic energy of a gas. It is denoted by

Chemical Principles: The Quest for Insight
- Urea, NH2CONH2, is a nitrogen fertilizer that is manufactured from ammonia and carbon dioxide. 2NH2(g)+CO2(g)NH2CONH2(aq)+H2O(l) What volume of ammonia at 25C and 3.00 atm is needed to produce 908 g (2 lb) of urea?arrow_forwardThe density of liquid oxygen is about 1.4 g/cm3. Vaporized at 00C and 760 torr, this same 1.4 g occupies 980 cm3, an expansion of 700 times the liquids volume.arrow_forwardYou have an equimolar mixture of the gases SO2 and O2, along with some He, in a container fitted with a piston. The density of this mixture at STP is 1.924 g/L. Assume ideal behavior and constant temperature and pressure. a. What is the mole fraction of He in the original mixture? b. The SO2 and O2 react to completion to form SO3. What is the density of the gas mixture after the reaction is complete?arrow_forward
