Consider the following equilibrium at 1000K: 

2SO2 (g) + O2 (g) ↔ 2SO3 (g)

A study of this system reveals that there are 3.2E-3 moles of sulfur dioxide gas, and 4.4E-3 moles of oxygen gas present in a 13.0L flask at equilibrium. The equilibrium constant for this reaction is 4.5E-3. Calculate the number of moles of SO3(g) in the flask at equilibrium.

2,H2O(g) + CO(g)<_>CO2(g) + H2(g)

is 3.00×103. What is the equilibrium constant, at the same temperature, for the following reaction?

H2g+CO2g<_>COg+H2Og

DATA:

Moles of SO2 = 3.2*10-3mol = 2.461*10-4 M

Moles of O2 = 4.4*10-3 mol = 3.3846*10-4M

Keq = 4.5*10-3

Moles of SO3 =?

SOLUTION:

Keq = [SO3]2/[SO2]2[O2]

[SO3]2 = Keq *[SO2]2[O2]

[SO3]2 = (4.5*10-3)(2.461*10-4)2(3.3846*10-4)

[SO3]=3.0359*10-7M

Moles of SO3= 3.9467*10-6mol

do u know that they r tow questions?


May 8th, 2015

i couldn't understand the next part of the question.3.00*10-3 is what?

May 8th, 2015

yeah i know that but i believe some information is missing in that question. you need to tell me what is 3.00*103

ok thank you

May 8th, 2015

i don't know that is what is said in my homework

May 8th, 2015

did u got it?


May 8th, 2015

hello please did you got what iam taking about?

May 8th, 2015

this is the complete question please


At a given temperature, the equilibrium constant for the reaction

H2O(g) + CO(g)<___>CO2(g) + H2(g)

3.00E3  What is the equilibrium constant, at the same temperature, for the following reaction?

H2(g) + CO2(g)<___>CO(g) + H2O(g)


May 8th, 2015

okay please can i post one here to replace the one and best u?


May 8th, 2015

so you mean you are posting a different question?

May 8th, 2015

but i already bid u

May 8th, 2015

i best u already for that question

May 8th, 2015

thank you...i wish i could help you with other question

May 8th, 2015

yes please i have more i posted before tutors keep giving me wrong answers

DATA:
mol of PCl3 = (4.61*10-2 mol*1000)/5000=9.22*10-3 M

Mole of PCl5 = (6.83*10-2 mol *1000)/5000=1.366*10-2M

Mole of Cl2 = (5.22*10-2*1000)/5000= 1.044*10-2M

Keq =?

SOLUTION:

Keq = [PCl5]/[PCl3] [Cl2]

  = 1.366*10-2/(9.22*10-3) (1.044*10-2)

Keq = 141.912
