A sample of SO3 is introduced into an evacuated sealed container and heated to 600 K. The following equilibrium is established:
2SO3(g)?2SO2(g)+O2(g).
The total pressure in the system is found to be 3.0 atm and the mole fraction of O2 is 0.12.
Find Kp.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
