Module 1 & 2 Equations Flashcards
1
Q
pH of buffer
A
pH=pKa+log([Base]/[Acid] )
2
Q
pKw of buffer
A
pKw=pKa (Acid)+ pKb (Base)
3
Q
pKw
A
pKw=pKa (HA)+ pKb (A)
4
Q
What is c and C?
A
c is heat capacity, C is specific heat.
5
Q
c=
A
c=C/m
6
Q
Q
2
A
Q=mc∆T, or Q=C∆T
7
Q
∆rG^0
2
A
∆rG^0= ∆rH^0-T∆rS^0
or
∆rG^0= -RT ln(Q)
8
Q
∆rG
A
∆rG=∆rG^0+RT ln(Q)
9
Q
∆rH
A
∆rH= (-Q)/n
10
Q

A
ln[At ]=ln[A0 ]-kt
ln0.5=-kt
11
Q
k
A
k= 〖Ae〗^(-E_a/RT )
12
Q
lnk
A
lnk=(-E_a)/RT+lnA
13
Q
k at 2 temperatures
A
ln(k1/k2 )=-Ea/R ((1/T1) -(1/T2 ))
14
Q
rate
2
A
rate=k[A]^x [B]^y
rate=1/a×d[A]/dt=1/b×d[B]/dt…
15
Q
