The essential conditions for liquefaction of gases were discovered by Andrews in 1869 as a result of his study of pressure-volume-temperature relationship for CO_(2) . It was found that above a certain temperature, it was impossible to liquefy a gas whatever the pressure was applied. The temperature below which the gas can be liquefied by the application of pressure alone is called critical temperature (Tc). The pressure required to liquefy a gas at this temperature is called the critical pressure (Pc). The volume occupied by one mole of the substance at the critical temperature and pressure is called critical volume. Critical constants are related with van der waals' constant as follows: V_( c) = 3b, P_( c) =a/(27b^(2)), T_( c) =(8a)/(27 Rb) The values of critical volumes of four gases A, B, C and D are 0.025L, 0.312L, 0.245L and 0.432L respectively. The gas with larger molecular diameter will be :
Assertion:Reverse osmosis is used in the desalination of sea water. Reason: When pressure more than osmotic pressure is applied, pure water is squeezed out of the sea water through the membrane.
Ammonia under a pressure of 1.5 atm at 27^(@) C is heated to 374^(@) C in a closed vessel in the presence of a catalyst. Under the conditions, NH_(3) is partially decomposed according to the equation. 2NH_(3) hArr N_(2) + 3H_(2) the vessel is such that the volume remains etfectively constant where as pressure increases to 50 atm. Calculate the percentage of NH_(3) actually decomposed
The nitrogen gas pressure inside a container of volume 2.6 cm^(3) is 2.3 atm at 27^(@)C . The approximate number of moles of nitrogen present in the container is [ R=0.0821 L atm "mol"^(1)K^(-1) ]
A gas of volume 2000ml is kept in a vessel at a pressure of 10^3 pascals at a temperature of 27^@C . If the pressure is increased to 10^5 pascals at the same temperature, the volume of the gas becomes
What will be the pressure exerted by a mixture of 3.2 g of methane and 4.4 g of carbon dioxide contained in a 9 dm^3 flask at 27^@C ?
