cannot be liquified even at high pressures. ∴ When cooling starts from K, H O will liquify first, then followed by ammonia and finally carbondioxide will liquify. 11th Std Chemistry 11th Std Chemistry - - - - I Choose the correct answer: . (d) at high pressure the intermolecular interactions become significant .
(d) inversely proportional to the square root of its molecular weight . (c) P an nb nRT ( ) = . (b) exert no attractive forces on each other . (a) / .
(b) Boyle temperature . (c) diffusion . (b) near the hydrogen chloride bottle . (d) units of pressure and volume .
(c) . J mol - K - . (a) Boyle's Law . (c) NH .
(d) I, II and III . (c) . dm . (c) P .
(b) NH . (c) mol - L and L atm mol - . (d) both assertion and reasons are false . (c) .
g L - . (c) . (d) HI Keys to multiple choice questions: . mass of methane = mass of oxygen = a number of moles of methane = number of moles of Oxygen = mole fraction a a of Oxygen = Partial pressure of ox a a a a a ygen = mole fraction Total Pressure = P .
The temperature at which real gases obey the ideal gas laws over a wide range of pressure is called Boyle temperature EVALUATION 11th Std Chemistry 11th Std Chemistry - - - - . Rate of diffusion α /√M M NH3 = ; M HCl = . γ NH3 > γ HCl Hence white fumes first formed near hydrogen chloride . Higher the value of 'a', greater the intermolecular force of attraction, easier the liquefaction.
option (c) is correct . Compressibility factor z PV nRT z P ( )
