Kinetics & EQM

Kinetics and equilibria

TermDefinition
Activation energy Is the minimum amount of kinetic energy particles need to start the reaction
Rate of reaction the change in concentration of a substance in unit time
Le Chatelier's Principle If any factor that affects equilibrium is changed, the position of equilibrium will shift to oppose the change.
Catalyst Is a substance which speeds up the rate of reaction but remains chemically unchanged. They provide an alternative route which has a lower activation energy
Dynamic equilibrium occurs when forward and backward reactions are occurring at equal rates. The concentrations of reactants and products stays constant and the reaction is continuous.
Temperature increase If temperature is increased the equilibrium will shift to oppose this and move in the endothermic direction to try and reduce the temperature by absorbing heat.
Temperature decrease the equilibrium will shift to oppose this and move in the exothermic direction to try and increase the temperature by giving out heat.
The Maxwell-Boltzmann energy distribution shows the spread of energies that molecules of a gas or liquid have at a particular temperature
Catalysts do not affect the position of equilibrium
Effect of catalysts on Maxwell-boltzmann If the activation energy is lower, more particles will have energy > EA,so the reaction will be faster

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
