Ch 14 & 15(gas And Acid Quilibrium Flashcards
Reversing a reaction
Multiply or dividing reaction
Adding reactions
1/k
(K)^n or (k)^1/n
Krxn1 X Krxn2
Partial pressure
Pi = (M)RT
Kp= Pb/ Pa
Kp= Kc(RT)^delta n
Delta n = (coefficients of products coefficients of reactants)
Q rxn quotient
Products/ reactants
But use initial concentrations or pressures
Q>K
Q
Excess products
Lack of products
Equilibrium
Increase volume
Equi shifts to side with greater mols of gas
Decrease volume
Equi shifts to lesser side of mols of gas
Increase temperature
Equi shift away from heat side
Decrease temp
Equi shifts toward heat side
Strong acids
HCl, HBr, HI, HNO3, HClO4, H2SO4
Weak acids/ bases
Always in water
Amphoteric
Can act as base or acid
Water, hydrogen carbonate, HPO4^2-
