A gaseous substance ABhas a radioactive element A with a half life of 2 days. The gaseous substance decomposes to A_((g)) and B_((g)) in a closed container and an equilibrium gets established rapidly withina fraction of second . The substance to which A decays into is non gaseous and does not effect volume of the container. If at equilibrium total pressure is 4 atm and molar ratio of AB : Bis 2 :1then equilibrium constant will be

1.	A gaseous substance ABhas a radioactive element A with a half life of 2 days. The gaseous substance decomposes to A_((g)) and B_((g)) in a closed container and an equilibrium gets established rapidly withina fraction of second . The substance to which A decays into is non gaseous and does not effect volume of the container. If at equilibrium total pressure is 4 atm and molar ratio of AB : Bis 2 :1then equilibrium constant will be
Answer» `(1)/(2) ` PA `(1)/(2) xx 101325""`Pa `4 "atm"^(2)` 4 atm Solution :`{:(AB(g),HARR,A(g),+,B(g),"fractopm of second",),("a mole",,,,,,),(a-X,,x,,x,,),("2 moles",,1 "mole",1 "mole","Total pressure 4 atm",,),(,"mole RATIO"=AB : B,,,,,),(,2:1,,,,,),("Parital",2 "atm",1"atm",1 "atm",,,),(,k_(P)=(1)/(2)"atm",,,,,),(,k_(P)=(1)/(2)xx1.01325 xx 10^(5) "pascal",,,,,):}`
