Kc=5.85x10^-3 at 25 degrees C for the reaction

Question

N2O4(g)<-->2NO2(g)
fifteen(15.0) grams of N2O4 is confined in a 5.00-L flask at 25 degrees C. Calculate(a) the number of moles of NO2 present at equilibrium and(b) the percentage of the original N2O4 that is dissociated.

Answer 1

uhh if i new chemistry i will help but u should post the same question around 5:00 pm tommorow and name the subject ms.sue shes really helpfull and that's when she usally is on hope some1 helps u if not just post agian 2mmorow..:)

Answer 2

Convert 15.0 g N2O4 to moles and that divided by 5.0 L to obtain molarity.

Set up an ICE chart, substitute into Kc expression and solve.

Answer 3

what does it mean when it says the percentage of the original N2O4 that is dissociated.

Answer 4

oh drbob222 and srasomething???are really helpful 2 luckly u got a respawn:)

Answer 5

When you finish and know the equilibrium concn of N2O4, then (amt N2O4 present in grams/15.0)*100 = ?? I think you will get the percent answer if you use (moles at equil/original moles)*100 = ??
