Question: Describe the factors responsible for the deviation of the behaviour of real gases from that of an ideal gas.

Short Answer

Expert verified

Actual gases deviate from their ideal condition due to changes in temperature, pressure, and van der Waals attractions. Furthermore, when the size of the gas molecules grows larger, the gas's ideal behaviour begins to vary.

Step by step solution

01

Step 1: Define Gas

One of the four fundamental states of matter, a gas is made up of particles with no definite volume or structure.

02

Describing the factor responsible for the behaviour of real gas

The departure of real gases from that of an ideal gas is caused by lowering the temperature, raising the pressure, and van der Waals attractions. In addition, when the size of the gas molecules grows larger, the gas begins to diverge from its optimum behaviour.

Therefore, lowering the temperature, rising the pressure, and van der Waals attractions cause actual gases to diverge from their ideal state. Furthermore, when the size of the gas molecules increases, the gas begins to deviate from its ideal behaviour.

One molecule of haemoglobin combines with four molecules of oxygen. If \(({\rm{1}}{\rm{.0 g}}\) of haemoglobin combines with \(({\rm{1}}{\rm{.53 mL}}\) of oxygen at body temperature (\(({\rm{3}}{{\rm{7}}^{\rm{o}}}{\rm{C}}\)) and a pressure of \(({\rm{743 torr}}\), what is the molar mass of haemoglobin?

A balloon that is \(100.21\;{\rm{L}}\) at \({21^\circ }{\rm{C}}\)and \(0.981\)\({\bf{atm}}\) is released and just barely clears the top of Mount Crumpet in British Columbia. If the final volume of the balloon is \(144.53\;{\rm{L}}\) at a temperature of \({5.24^\circ }{\rm{C}}\), what is the pressure experienced by the balloon as it clears Mount Crumpet?

Before small batteries were available, carbide lamps were used for bicycle lights. Acetylene gas, C2H2, and solid calcium hydroxide were formed by the reaction of calcium carbide, CaC2, with water. The ignition of the acetylene gas provided the light. Currently, the same lamps are used by some cavers, and calcium carbide is used to produce acetylene for carbide cannons.

(a) Outline the steps necessary to answer the following question: What volume of C2H2at atm and 12.2虋C is formed by the reaction of 15.48g of CaC2with water?

(b) Answer the question.

The chlorofluorocarbon CCl2F2 can be recycled into a different compound by reaction with hydrogen to produce CH2F2(g), a compound useful in chemical manufacturing: CCl2F2 (g) + 4H2 (驳)鉄禖贬2F2 (g) + 2HCl(g)

(a) Outline the steps necessary to answer the following question: What volume of hydrogen at 225 atm and 35.5 掳C would be required to react with 1 ton (1.000 脳 103 kg) of CCl2F2?

(b) Answer the question

If the volume of a fixed amount of a gas is tripled at constant temperature, what happens to the pressure?
