._(Z)^(M)A(g)to ._(Z-4)^(M-8)B(g)+(alpha-"particles") (alpha.particle – InterviewSolution

1.	._(Z)^(M)A(g)to ._(Z-4)^(M-8)B(g)+(alpha-"particles") (alpha.particles are helium nuclei, so will form He gas by trapping electrons). The radioactive disintergration follows 1st order kinetics, starting with 1 mole of A in a 16.4 litre closed flask at 127^(@)C. pressure (atm) developed after two half lives is : (R = 0.082 "litre atm"//"mol-K")
