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)
Initial moles of gases = 1
Inital moles 1 moles
Moles after decompostion 8 mole
Total gaseous moles after decompostion = 8 + 1 = 9 moles
Ratio of pressures
