- Equations- Equilibrium, Rates & pH
- rate of reaction= ^conc.(products/ reactants) ÷ time
- rate = k[A] [B]
- K= rate/ [A] [B]
- Kc=[products] [reactants]
- k = ln2 ÷ t(1/2)
- gradient= ^y÷^x
- k= Ae-Ea/RT
- k= rate constant
- T = temperature
- A=pre exponential factor
- -Ea= activation energy
- R= gas constant
- e=inverse natural log
- mole fraction= number of moles (substance A) ÷ total number of moles
- partial pressure= mole fraction x total pressure
- Ka=[H+][A-] ÷[HA]
- Ka= 10-pKa
- pKa= -log10[Ka]
- [H+]= ?Ka x [HA]
- Kp= p(products)/ p(reactants)
- Kw=[H+][OH-]
- [H+]=Kw÷ [OH-]
- A=e (LnA)
- m= -Ea ÷ R
- lnK= LnA - (Ea÷R) x (1÷T)
