Equilibrium
Equilibrium and Acid Base Theories
| Term | Definition |
|---|---|
| What occurs at equilibrium? | The rate of the forward reaction equals that of the reverse |
| When all coefficients in a rate law are doubled, what must the Kc do? | It must be squared |
| When all the coefficients in a rate law are halved, what must the Kc do? | The square root must be taken |
| When writing the Kc or Kp, what is the denominator? | The reactants are the denominators |
| The reaction is product favored if the Kc is | large |
| When heat is added | the reaction goes to the side away from the side in which the heat appears on |
| When heat is taken away | the reaction goes towards the heat to replace it |
| Catalysts | do not affect equilibrium |
| If a noble gas is added at constant volume | there will be a change because the pressure will increase |
| A decrease in volume increases the pressure | and causes a shift that favors less moles of a gas |
| An increase in volume decreases the pressure | and causes a shift that favors more moles of gas |
| If a common ion is added | shift away from that ion |
| What is the relationship between Ka, Kb and Kw? | Ka+ Kb= Kw |
| What is Kw? | It is 1.0x10^/14 |
| How do you find the pH using the Molarity? | pH=-log[M] |
| What must be remembered for the sig figs of Acids and Bases? | Sig figs start AFTER the decimal point |
| What is different about the Ice Boxes of acids and bases? | You must take the negative logs of the concentrations at the end |
| What is the difference between a strong acid and a weak one? | Strong acids will ionize COMPLETELY. |
