____ increase roughly doubles rate and k
10°C
loge =
ln
ln(e) =
1
ln(AB) =
lnA + lnB
ln(A/B) =
lnA - lnB
ln(A)² =
2ln(A)
y = mx + c version of Arrhenius equation
lnk = -Ea/R × 1/T + lnA
Ionic product of water equation
Kw = [H+][OH-]
partial pressure =
mole fraction × total pressure
larger Ka means
stronger (weak) acid
What assumptions do Ka calculations make?
That the acid concentration doesn’t change (the concentration of acid is the same at equilibrium as it is at the undissociated)
That the concentration of water is constant.
To find pH with [H+], do…
-log(H+)
To find [H+] with pH, do…
10^(-pH)
Name a weak base
NH3
How do you know which indicators will be suitable based on an acid graph?
The suitable indicators are all within the vertical position (the shaded area has no curve)
