A gaseous substance AB has 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 within a 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 : B ` is `2 :1` then equilibrium constant will be
A. `(1)/(2) ` Pa
B. `(1)/(2) xx 101325""`Pa
C. `4 "atm"^(2)`
D. 4 atm
