The decomposition of a compound P, at temperature T according to the equation 2P_((g)) rarr 4Q_((g)) +R_((g)) +S_((l))is the first order reaction. After 30 minutres from the start of decomposition in a closed vessel, the total pressure developed is found to be 317 mm Hg and after a long period of time the total pressure observed to be 617 mm Hg. Calculate the total pressure of the vessel after 75 mintute, if volume of liquid S is supposed to be negligible. Also calculate the time fraction t_(7//8). Given : Vapour pressure of S(l) at temperature T = 32.5 mm Hg

1.	The decomposition of a compound P, at temperature T according to the equation 2P_((g)) rarr 4Q_((g)) +R_((g)) +S_((l))is the first order reaction. After 30 minutres from the start of decomposition in a closed vessel, the total pressure developed is found to be 317 mm Hg and after a long period of time the total pressure observed to be 617 mm Hg. Calculate the total pressure of the vessel after 75 mintute, if volume of liquid S is supposed to be negligible. Also calculate the time fraction t_(7//8). Given : Vapour pressure of S(l) at temperature T = 32.5 mm Hg
Answer» <P> SOLUTION :`p_(t)=379.55" MIN HG, "t_(7//8)=399.96` min
