|---|---|---|---|---|---|
| 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.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
