One of the approach to the study of real gases involves the analysis of a parameter Z called the compressibility factor Z=(PV_(m))/(RT) where P is pressure, V_(m) is molar volume, T isabsolute temperature and R is the universal gas constant . Such a relation can also be expressed as Z =((V_("m real"))/(V_("m ideal")))(where V_("m ideal ") and V_("m real") are the molar volume for ideal and real gas respectively) . Gas corresponding Z gt 1 have repluive tendenciesamong constituent particles due to their size factor, among constitutent particles . As the pressure is lowered or temperature is increased the value of Z approaches 1. ( reaching the ideal behaviour) For a real gas 'G'Z gt 1 at STP then for 'G' which of the following is true

1.	One of the approach to the study of real gases involves the analysis of a parameter Z called the compressibility factor Z=(PV_(m))/(RT) where P is pressure, V_(m) is molar volume, T isabsolute temperature and R is the universal gas constant . Such a relation can also be expressed as Z =((V_("m real"))/(V_("m ideal")))(where V_("m ideal ") and V_("m real") are the molar volume for ideal and real gas respectively) . Gas corresponding Z gt 1 have repluive tendenciesamong constituent particles due to their size factor, among constitutent particles . As the pressure is lowered or temperature is increased the value of Z approaches 1. ( reaching the ideal behaviour) For a real gas 'G'Z gt 1 at STP then for 'G' which of the following is true
Answer» 1 MOLE of the gas occupies 22.4 L at NTP 1 moleof the gas occupies 22.4 L atpressure HIGHER than that at STP (keeping temperature constant) 1 mole of the gas occupies 22.4 L at pressure lower than that at STP ( keeping temperature constant) None of the above Solution :`Z=(PV_(m))/(RT) gt 1` `(PV_(m))/(RT)= (1xx22.4)/(R xxT ) ` At same pressure `=1` atm `(1xxV_(m))/(RT) gt (1 xx 22.4)/(R xx T ) implies V_(m) gt 22.4 L ` at STP for real gas. For `V_(m) = 22.4 L` of real gas , we have to increase the pressure.
