A_((g)) overset(Delta)to P_((g)) + "Q"_((g)) + R_((g)) , follows first order kinetics with a half life of 69.3 s at 500^(@) C. Startingfrom the gas ‘A’ enclosed in a container at 500^(@) C and at a pressure of 0.4 atm, the total pressure of the system after 230 s will be

Answer»

<P>1.15 atm
1.32 atm
1.22 atm
1.12 atm

Solution :`(230)/(69.3) = 3.33 ` HALF lives
90% COMPLETION
`underset(1-0.9)(A_((g))) implies underset(0.9)(P_((g))) + underset(0.9)(Q_((g))) + underset((0.9))(R_((g))) = 0.1`
Total PRESSURE = 0.1 + 0.9 + 0.9 + 0.9 = 2.8
` 1-0.4`
`2.8 - ?`
` 2.8 xx 0.4 = 1.12 atm`
