Re: 2014 Final Question 6 Given information
Looks like students only had to draw arrows. Because part of it says, "Draw curved arrows in the mechanism below" and doesn't mention drawing the mechanisms.

Endothermic vs Exothermic
I am confused on how to determine if a reactions is endothermic or exothermic. Previous posts discuss that the deltaH tells you. How do we know what deltaH is in a problem like Q6 on the 2010 Final? The problem has us solve for the equilibrium concentrations of N2O4 and NO2 and draw their lewis stru...

Sig Figs involving pH
My TA discusses how the significant figures only count for the number behind the decimal point and not before the decimal point when dealing with pOH and pH. Why is this so? An example problem is: pOH= -log(9.7 x 10^-6) = 5.01 (Only 2 sig figs, not 3). Then pH= 8.99 (Again, only 2 sig figs, not 3).

When are you allowed to just drop the x value when finding the equilibrium concentration, so you do not need to use the quadratic formula? For this problem, Kc=1.93= (0.0050 + 2x)^2 / (0.010 - x).
