A closed vessel with rigid walls contains 1 mole of ""_(92)^(238)U and 1 mole of air at 298K. Considering complete decay of ""_(92)^(238)U to ""_(82)^(206)Pb, the ratio of the final pressure to the initial pressure of the system at 298K is…..

Answer»


SOLUTION :`""_(92)^(238)U RARR ""_(82)^(206)P + 8 ""_(2)^(4)He + 6 ""_(-1)^(0)e`
`(P_("final"))/(P_("intial"))= (8 (He) + 1 ("air"))/(1("air"))`
