Chapter 5 & 10: Thermochemistry & Gases Flashcards
1
Q
state function
A
-how you get to the final answer(path) is not important but what results from it si what matters
2
Q
how can you convert moles to heat
A
-mole to heat ratio (kJ)
3
Q
is delta heat of rxn a conversion factor?
A
-no
4
Q
when does delta H equal q?
A
-@ constant pressure
5
Q
when you can’t measure the temp of the system directly, what do you do?
A
qsys= -qsurr (based on Q) qrxn= -qsoln OR q(element)= -(qh2O+qcalorimeter)
6
Q
q of rxn equals what?
A
kJ/mol
7
Q
what is the density equation?
A
Mm=(dRT)/P
8
Q
as speed increases, what happens to KE?
A
it increases
