A closed vessel with rigid walls contains 1 mol of \(^{238}_{92}U\)

1.	A closed vessel with rigid walls contains 1 mol of \(^{238}_{92}U\) and 1 mol of air at 298 K. Considering complete decay of \(^{238}_{92}U\) to \(^{206}_{82}\) pb, the ratio of the final pressure to the initial pressure of the system at 298 K is
Answer» In conversion of \(^{238}_{92}U\) to \(^{206}_{82}Pb\) , 8α - particles and 6β particles are ejected. The number of gaseous moles initially = 1 mol The number of gaseous moles finally = 1 + 8 mol; (1 mol from air and 8 mol of ₂He⁴) So the ratio = 9/1 = 9

Answer»

In conversion of \(^{238}_{92}U\) to \(^{206}_{82}Pb\) , 8α - particles and 6β particles are ejected. The number of gaseous moles initially = 1 mol

The number of gaseous moles finally = 1 + 8 mol; (1 mol from air and 8 mol of ₂He⁴)

So the ratio = 9/1 = 9
