I have a couple problems and questions...

First, you have this: 2A(aq) + B(aq) -> 3C(aq) + D(aq)

I need to determine Kc if 6 moles of A + 6 moles of B in 2L solution yeild .10 moles of D at Equalibrium.

^the answer from setting up the ICE (inital, change, equalibrium)Chart and using the Equalibrium Constant is 6.8X10^-6.

Problem: Determine the moles of B to be added to double the concentration of D?

Second question i have has to deal with Heterogeneous equalibriums. I understand we ommit phases that are in liquid or solid, and i have this Ti(s) + 2Cl_2(g) = TiCl_4(l).
Would Kc = /[CL_2]^2 ??

Thanks,
Tony

 

Yeah I got a C+ in Chem1A, so yeah....

 

I should know this since I just finished up O-chem.

 

Thats hilarious because Its exactly what i was thinking. Like shittt, O chm i so freaking hard compared to regular chm, why dont i know this! Just goes to show how most of the crap you learn leaves when the semester finishes...

 

to think i actually got an A in chem 1 and 2 back like 3 years ago and now this stuff is like a foreign language
