|---|---|---|---|---|---|
| Can equilibium constant (K eq) ever be negative? | no
🗑
|
||||
| K(eq) < 1 means... | reaction favors the reactants
🗑
|
||||
| K(eq) > 1 means... | reaction favors the products
🗑
|
||||
| lowering temp favors... | exothermic reactions
🗑
|
||||
| raising temp favors... | endothermic reactions
🗑
|
||||
| Q > K(eq) means... | the reacton procedes in the reverse
🗑
|
||||
| Q < K(eq) means... | the reaction procedes forward
🗑
|
||||
| Exothermic reactions are located.... and ∆H is... | on the product side; negative
🗑
|
||||
| Endothermic reactions are located... and ∆H is ... | on the reactants side; positive
🗑
|
||||
| Adding a catalyst to a reaction that is already at equilibrium will have what kind of effect... | adding a ( ) increases the rate of both the forward and reverse reactions equally, hoewever the equilibrium amounts will not change
🗑
|
||||
| In a reaction at equlibrium, if the volume is reduced, therefore increasing the pressure, a net reaction occurs favoring... | the side with the smaller total number of moles
🗑
|
||||
| In a reaction at equlibrium, if the volume is expanded, therefore decreasing the pressure, the net reaction occurs favoring... | the side with the greater total number of moles
🗑
|
||||
| What will happen to a reaction's equilibrium contsant K(eq) if the temp changes? | The value of K(eq) is constant at a given temp therefore if the temp changes so does the K(eq)

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.
