Enthalpy Of Solution + Entropy Flashcards
1
Q
Definition
A
When 1 mole of an ionic substance is dissolved in the minimum amount of solvent to ensure no further enthalpy change upon dilution
2
Q
Hydration enthalpy
A
Enthalpy change when one mole of gaseous ions is dissolved on water to form one mole of aqueous ions under standard conditions
3
Q
Equation Solution
A
Hydration - solution
4
Q
Entropy definition
A
Measure of disorder
5
Q
Entropy 1
A
More distorter the greater the entropy
Increases from solid to gas
Bcs temp increases
They gain more energy and move further apart
6
Q
Num of particles entropy
A
More moles = more entropy
7
Q
Stability
A
More disorder = more stability
Why some reactions are feasible even when endothermic
8
Q
Entropy equation
A
Products - reactants
