Flashcards in The Rate and Extent of Chemical Changes Deck (10):
1

What is the Rate of Reaction?

The rate of a chemical reaction is how fast the reactants are changed into products.

2

What is the rate of reaction?

The rate of reaction is how fast the chemicals are turned into products.

3

What is one of the slowest chemical reactions?

The rusting of iron.

4

What is one of the fastest?

Burning and explosions.

5

How can you find the speed of a reaction?

You can find the speed of a reaction by recording the amount of product that is formed.

6

What does the rate of a chemical reaction depend on?

The rate of a chemical reaction depends on the collision frequency of the reacting particles and the energy that is transferred during a reaction.

7

What are the factors affecting the rate of reaction?

Temperature, Concentration, Surface Area and the presence of a catalyst.

8

What is the equation for Rates of Reaction?

The equation is: Rate of Reaction = Amount of reactant used or product formed divided by Time.

9

How do you calculate and find the speed of a reaction?

You can find the speed of a reaction by recording the amount of product that is formed. The steeper the graph the faster the rate of reaction.

10

What is the Collison Theory?

The Collision Theory is the theory that is used to explain reaction rates. The rate of a reaction depends on the collision frequency of the reacting particles and it also depends on the energy that is transferred during a reaction.
