(B) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion
 
(C) Assertion is correct, but reason is wrong statement
 
(D) Assertion is wrong, but reason is correct statement
 
(E) Both assertion and reason are wrong statements
 
1 [A]:Surface tension of a liquid decreases with increase in temperature
[R]: At higher temperature interparticle forces are greater.
 
2 [A]:Three states of matter are the result of balance between intermolecular forces and thermal energy of the molecules
[R]:Intermolecular forces tend to keep the molecules together but thermal energy tends to keep the molecules apart
 
3 [A]: boiling point of a liquid cannot be altered by changing the pressure over the liquid.
[R]: Higher the pressure over the liquid, lower the boiling point.
 
Answer the following questions:
 
1 What type of intermolecular forces exists between the following? HCl and H2O ii F2 molecule iii Br— and H2O iv CO2 and ammonia
 
2 At a certain temperature, a certain mass of gas occupies a volume of 5dm3when the pressure is 540mm of Hg. Calculate the pressure in atmosphere when the volume is reduces to 1.5 dm3 at the same temperature.
 
3 At a constant temperature, a certain mass of gas occupies 7.5 L when the pressure is 800mm of Hg. Calculate the pressure at which the volume of the gas would be decreases by 35% of its initial volume.
 
4 The temperature of a given mass of air was reduced from 150C to -150 C. If the initial volume of air was 100ml, what would be its new volume if pressure is maintained a constant?
 
5 Calculate the volume occupied by 0.5 moles of CO2 at -250C and 760mm pressure. [At STP volume is 22.7 L/mole]
 
6 The density of a gaseous oxide at 2 bar is the same as that of nitrogen gas measured at 5 bar at a given temperature. Find the molar mass of the oxide.
 
7 What will be the pressure of a gaseous mixture containing 4.2 g of nitrogen and 1.6 g of methane in a 5 L flask at 27oC?
 
8 The density of a gas was found to be 1.56g/Lat 745mm of Hg and 65oC. Calculate its molecular mass.
 
9 Using the equation of state PV= nRT show that at a given temperature, the density of a gas is proportional to pressure.
 
10 Derive
a) The relation between partial pressure of a gas and its mole fraction.
b) The ideal gas equation
c) Relation between density of a gas and its molar mass
 
11 a) In terms of Charles laws explain why -273oC is lowest possible temperature?
 
b) Explain the term absolute zero.
 
12 a) What do you understand by critical temperature, critical pressure and critical volume of a gas?
 
b) Critical temperature for carbon dioxide and methane are 31.1oC and -81.9oC respectively. Which of these has stronger intermolecular forces and why?
 
13 a) What do you mean by ideal and real gases?
b) Why do real gases deviate from ideal behaviour?
c) Write Van der Waals equation for real gases.
