The discussion revolves around calculating equilibrium concentrations and equilibrium constants (Kc) for two chemical reactions. The first reaction involves N2 and O2 producing NO2, with given concentrations for N2 and O2, and Kc of 1.6 x 10^-17. The second reaction concerns the formation of SO3 from SO2 and O2, where the user calculated Kc to be 1 after placing 4 moles of SO3 in a 2L container. Participants suggest that the user should seek help on dedicated chemistry boards, emphasizing the importance of attempting the problems independently first. Ultimately, the user confirms they solved the problems correctly.

i have 2 questions, i just don't seem to get , here it goes

at 25 degrees, kc = 1.6 x 10^-17 for the reaction

N2(subscript) (g) + 2O2(subscript)(g) ---- 2NO2(subscript)(g)

concentration of N2 = .0320 mol^-1
concentraion of O2 = .00860 molL^-1

calculate equilibrium concentraion of NO2(g)


the second question is :

for the following rxn

2SOsubscript2 (g) + Osubscrupt2(g) ---- 2SOsucript3 (g)

calculate valua of kc if 4 mol of SO3 is placed in a 2L container and allowed to reach equil.

equililbrium concentration of O2 = .500 mol/L^-1

can someone help please?
 
Physics news on Phys.org
my answer for kc was 1 for the 2nd question , can anyone verify that?
 
i guess everyones hates me ^_^
 
I'm no expert in Chemistry, but I can say that there aren't many chemists on these boards. Maybe you should try posting on the Chemistry boards if you have not already.
 
HW policy is that you take at least a blind swing at the problem.

"One" looks good for Q2.
 
i did take a swing at them both, that's why I am posting them here :D...but nvm now i got them right thanks for "attempting" to help everyone haha

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
