---|---|---|---|---|---|
Entropy | measure of degree of randomness as particles move; more random = more entropy
🗑
|
||||
Enthalpy Change | using Hess's law; process equals the sum of the energy difference of products minus the sum of the energy difference of the reactants
🗑
|
||||
Chemical Equilibrium | Rate of forward reaction equals rate of reverse reaction and the concentrations of products and reactants remain unchanged
🗑
|
||||
Activated Complex | the maximum energy point along the reaction path
🗑
|
||||
Activation Energy | the minimum energy that must be input to a chemical system with potential reactants to cause a chemical reaction
🗑
|
||||
Collision Theory | qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions
🗑
|
||||
Catalyst | a substance that speeds up a chemical reaction, but is not consumed by the reaction
🗑
|
||||
Reversible reaction | Products can react to re-form the reactants
🗑
|
||||
∆H | enthalpy of products - enthalpy of reactants
🗑
|
||||
Hess's Law | Overall enthalpy change in a reaction is equal to the sum of the enthalpy changes for the individual steps in the process.
🗑
|
||||
Endothermic | Heat energy is absorbed; products higher
🗑
|
||||
Exothermic | Heat energy released; products lower
🗑

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.
