### 11.33

Posted: Mon Jul 24, 2017 7:23 pm
I am having trouble understanding 11.33, I am confused to how when solving for Qc we are dividing the values by 0.500 and how now the values we are given wen from 0.10 to 1.0 x 10^4? Also, question on why the values of kc changed and how exactly the calculations were done for that to change to 6.9?

is that same for why the Kc and Qc had changed? or is that just answering the first part of the question which is why the nmoles converted to moles?

oh, that answer was just for the first part but you do calculate Q and K the same.

You divide the moles by 0.500 because you need to find the concentration of the various gases by using: concentration = moles/volume (liters).
