Reaction Rate

Rates of Reaction Basics Chapter 18.1

TermDefinition
Activation Energy the amount of energy needed in order for particles to react when they collide.
2 things that affect reaction rate frequency of collisions amount of energy with which they collide
5 things that affect frequency of collisions and the amount energy in a reaction temperature, pressure, surface area, concentration, catalyst
As a reaction progresses the rate decreases because why? The reactants are getting used up and the products being produced are interfering with the collisions
In order for a reaction to take place, the particles must ________________ with each other. collide
What does a catalyst do that changes the reaction rate? It lowers the activation energy
What are some examples of how catalysts are used in industry? Catalytic converter, margarine production, laundry detergent
Is a catalyst an active reactant in a reaction? No, it remains unchanged
If the temperature is raised the reaction rate will ________. Increase
If the pressure is decreased the reaction rate will ______. decrease
As a reaction takes place, the reactants are getting used up and the products being produced are interfering with the collisions, what does this mean for the reaction rate? It will slow down and eventually stop when the product is at 100%.
What did the breathe fire lab demonstrate? That increased surface area increases the reaction rate.
What did the water to oil lab demonstrate? That some reactions can seemingly take place in an instant
What did the elephant toothpaste lab demonstrate? The use of a catalyst can increase the reaction rate greatly and can produce heat. (Exothermic)

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.
