Answer:
Total pressure 5.875 atm
Explanation:
The equation for above decomposition is
rate constant
Half life
Initial pressure
Pressure after 3572 min = P
According to first order kinematics
solving for P we get
P = 2.35 atm
initial 4.70 0 0
change -2x +2x +x
final 4.70 -2x 2x x
pressure of after first half life = 2.35 = 4.70 - 2x
x = 1.175
pressure of after first half life = 2x = 2(1.175) = 2.35 ATM
Total pressure = 2.35 + 2.35 + 1.175
= 5.875 atm
