A closed vessel with rigid walls contains 1 mol of 
and 1 mol of air at 298 K. Considering complete decay of 
to 
, the ratio of the final pressure to the initial pressure of the system at 298 K is
Text Solution
Verified by ExpertsThe correct answer is:
9
(9)In conversion of 
to 
, 8 
- particles and 6 
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
