[CHM 330] Still responding...

[Andrew J. Pounds]

Students -- I got my COVID booster on Friday afternoon and am now "down" 
with fever and many of the other COVID symptoms.  It's a big weekend for 
many of you to knock out some homework.  I will try to check e-mail 
every few hours and respond to questions, but my pace is a bit slower 
this weekend for obvious reasons.


One thing that I did want to try to clear up because several of you have 
asked about it relates to the notation that the book uses.  When you see 
in your text ΔrX\Delta_r X, where X is some quantity, it is referring to 
that quantity for the reaction.

ΔrX=ΔXrxn=∑i=1PRODniXi−∑j=1REACTnjXjΔ_rX=\Delta 
X_{rxn}=\sum_{i=1}^{PROD}n_i X_i −\sum_{j=1}^{REACT}n_j X_j

This is shown for enthalpy in equation 2.28 of your text -- but I wanted 
you to be able to compare it to the notation I use in the slides which 
is more general.  Also, some of you have asked about how to convert 
between CpC_p and CvC_v.  The conversion is shown in equatino 2.48 of 
the text.

Keep the questions coming.  We'll get through this!
