1.	1.2 moles of SO_(3)are allowed to dissociate in a 2 litre vessel the reaction is 2SO_(3(g)) hArr2SO_(2(g)) +O_(2(g))and the concent ration of oxygen at equilibrium is 0.1 mole per litre. The total number of moles at equilibrium will be
Answer» 2 1.4 0.8 1.6 Solution : Given `(O_(2))=(x)/(2)=0.1 IMPLIES x=0.2` TOTAL no. of moles at EQUILIBRIUM` = 1.2-2x+2x+x=1.2+x=1.4`
