| solve rate law | keep 1 trial constant then divide and solve for exponent
🗑
|
||||
| minimum energy 4 reactants to form products | activation energy
🗑
|

| has greater energy than either reactants /products | transition energy= breaking old bonds and new bonds forming
🗑
|
||||
| ________ the potential energy for products is less than the reactants | exothermic (negative heat rxn)
🗑
|
||||
| temperature changed Ea, true / false | false
🗑

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.
