How can the section order be determined in kinetics?
Can only be determined experimentally
Ex: The reaction order can be 2 even for reactions involving one reagent
What is the formula to calculate delta Go?
Delta Go = -RTlnKe
What interactions can be established by water?
Hydrogen bonds
What is the formula to calculate the osmotic pressure?
pi = cRT
C = efficient concentration that you have to calculate from Mxi
i = 1+ alpha (v-1)
What is the atomic radius ?
It is a periodic property
What is the state equation for ideal gases?
PV = nRT
What values does R assume?
When P = Pa, V = m3, T = K):
R = 8,314 J/molK
When P = atm, V = L, T = K)
R = 0,082 L atm/molK
When P = torr, V = L, T = K)
R = 62,36 torr L/molK
What is the formula to calculate the pH of an acidic solution (of a weak acid)?
Radice di Ka x Ca
(for the base it’s the same)
What is the formula to calculate the pH in a buffer solution (acidic)?
pH = pKa + log (Base coniugata/Acido)
(For a basic one it’s the same)
