A closed vessel with rigid walls contains 1 mol of U92238 and 1 mol of air at 298 K. Considering complete decay of U92238 to Pb82206 , the ratio of the final pressure to the initial pressure of the system at 298 K is

Solution

Initial moles of gases = 1


Total gaseous moles after decomposition =8+1=9 moles
Ratio of pressures, PfPi=nfni=9
