What does rate of reaction measure?
How much product is formed over in a fixed period of time
1 of 14
What is a limiting reactant?
The reactant not in excess that gets used up by the end of the reactant
2 of 14
What are the four ways of speeding up a reaction?
concentration, temperature, pressure and surface area
3 of 14
How does concentration speed up the reaction?
It increases the number of particles so they become more crowed
4 of 14
How does temperature speed up the reaction?
By warming the particles up, they then have more kinetic energy
5 of 14
How does pressure speed up the reaction?
Pressure forces the particles together
6 of 14
How does surface area speed the reaction up?
Having a large surface are the more the particles can react with each other.
7 of 14
What is collision frequency?
The amount of successful collisions between reacting particles each second
8 of 14
What does a catalyst do?
A catalyst speeds up a reaction without using itself up
9 of 14
Do endothermic reactions break bonds or make bonds?
Break bonds
10 of 14
Do exothermic reactions break bonds or make bonds?
Make bonds
11 of 14
What is the definition for allotropes?
Allotropes are different structures of an element
12 of 14
Why is graphite good at conducting electricity?
The electrons are free
13 of 14
Which 2 allotropes have a covalent bond?
Diamond and graphite
