Vedclass · Answer

(C) To determine which gas shows real behavior,we check if it follows the ideal gas equation $PV = nRT$.For option $A$: $n = \frac{16}{32} = 0.5 \ mol$. At $STP$,$V = n 	imes 22.4 \ L = 0.5 	imes 22.4 = 11.2 \ L$. This follows ideal behavior.For option $B$: $n = \frac{1}{2} = 0.5 \ mol$. Using $PV = nRT$,$P = \frac{nRT}{V} = \frac{0.5 	imes 0.0821 	imes 300}{0.5} = 24.63 \ atm$. This follows ideal behavior.For option $C$: $n = 1 \ mol$,$T = 300 \ K$,$P = 1 \ atm$. Ideal volume $V = \frac{nRT}{P} = \frac{1 	imes 0.0821 	imes 300}{1} = 24.63 \ L$. The given volume is $22.4 \ L$,which deviates from the ideal volume at $300 \ K$. Thus,$NH_3$ shows real behavior.For option $D$: $n = \frac{5.6}{22.4} = 0.25 \ mol$. Mass $= 0.25 	imes 44 = 11 \ g$. This follows ideal behavior.
