|
How do you calculate rate of reaction? |
Rate of reaction = Amount of reactant used/Time taken |
|
|
What is rate of reaction measured in? |
g/s, cm3/s, mol/s |
|
|
How does concentration affect chemical reactions? |
If concentration is higher, there will be more collisions as there are more reactants and therefore a higher rate of reaction |
|
|
How does pressure affect chemical reactions? |
If there is a higher pressure, there will be more collisions and there for a higher rate of reaction |
|
|
how does temperature affect chemical reactions? |
The higher the temperature, the more thermal energy that particles have. This means that there are more collisions and therefore a higher rate of reaction. |
|
|
What is a catalyst |
A catalyst is a substance that speeds up a chemical reaction or lowers the activation energy |
|
|
What is a reaction profile? |
A reaction profile shows how the energy of the reactants and products changes during a reaction |
