initial concentration of I = 0.000272 mol/ 10.0 L= 0.0000272 M
I2 < => 2 I
start
. .. . . 2.72 x 10^-5
change
+x .. . . -2x
at equilibrium
x .. . . . .2.72 x 10^-5 - 2x
3.1 x 10^-5 = ( 2.72 x 10^-5-2x)^2 / x
solve for x = [I2]
moles I2 = 10.0 x
mass I2 = moles I2 x 253.808 g/mol
moles SO3 = 1.30 g/80.066 g/mol=0.0162
[SO3] = 0.0162 / 2.00 L=0.00810 M
moles O2 = 0.106 g/ 32 g/mol=0.00331
[O2]= 0.00331/ 2.00 L=0.00166 M
Kp = Kc (RT)^delta n
delta n = 2 - 2 - 1 = -1
3.0 x 10^4 = Kc ( 0.08206 x 700)^-1 = Kc 0.0174
Kc = 1.72 x 10^6 = (0.00810)^2 / [SO2]^2 x 0.00166 = 0.0395/ [SO2]^2
[SO2]= 0.000152 M
moles SO2 = 0.000152 x 2.00 L=0.000304
mass SO2 = 0.000304 mol x 64.066 g/mol=0.0195 g
