1
Q
Keq Varies With
A
- Temperature ONLY
2
Q
Reaction Quotient
A
- The reaction quotient, Qrx, is the expression of products over reactants when the system is not at equilibrium
- If the Qrx is greater than the Keq, then the reaction will proceed towards reactants
- If the Qrx is less than the Keq, then the reaction will proceed towards the products
3
Q
Addition of Solid to a System in Equilibrium
A
- Has no effect on the equilibrium
4
Q
Solubility Rules
A
- Nitrates are almost always water soluble
- Transition metals and sulfate are insoluble
- Most salts with -2 and -3 anions are insoluble in water
- See sulfates above
- Most oxides and hydroxides are partially water soluble
