b. The large partial pressure of PCl5 at equilibrium
suggests that PCl5 is favored (products). The large equilibrium constant also suggests the same thing.
a) At 800K the equilibrium constant for
if an equilibrium mixture in a 10 L vessel contains
g of I how many grams of
are in the mixture?
. You have the weight of I. You can convert that to moles (the usual concentration units are moles / liter when they calculate Kc).
I won't do the rest for you (I'm too lazy.) You'll have to convert the masses of SO3 and O2 to moles and then use the ideal gas law,
at T=700 Kelvins to get the volume of each gas. Since it's not otherwise stated, I would use P = 1 atmosphere.
Once you solve the equation for the pressure of SO2, you'll have to convert that back to the number of moles of SO2 and from that you can calculate the mass.
