1.	5 moles of SO_(2) and 5 moles of O_(2) react in a closed vessel. At equilibrium 60% of the SO_(2) is consumed . The total number of gaseous moles(SO_(2),O_(2)andSO_(3))in the vessel is :-
Answer» 5.1 3.9 10.5 8.5 Solution :`{:(,2SO_(2),+,O_(2),hArr,2SO_(3)),("INITIAL moles",5,,5,,0),("At equilibrium",5-3,,5-(3)/(2),,3(5xx(60)/(1000)=3)):}` Total number of moles in the vessel`=2+3.5+3=8.5`
