| What does the Rate of a Chemical Reaction depend on? | -This is all Dependent on:
-Collision Frequency of the Reacting Particles. If they have more Successful Collisions, then they will be Faster
-Energy Transferred in the Collision has to be Enough so that it can React.
-The above is called Collision Theory |
| How can the Temperature affect the Rate of Reaction? | -This is because an Increase in the Temperature leads to a Faster Movement, because of more Kinetic Energy given to the Particles
-Higher Temperatures also will Increase the Energy of the Collisions, so that means there will be a Greater Chance for the Collisions to React.
-So Temperature increases the Number of Successful Collisions |
| How can the Concentration/Pressure affect the Rate of Reaction? | -If the Solution is more Concentrated, that means there is more Particles of Reactants, in the Same Volume
-This makes Collisions more Frequent, so more Reactions takes Place
-Pressure, in a Gas, also has the Particles more Crowded, so therefore it will have more Collisions |
| How can the Size, or Surface Area, affect the Rate of Reaction? | -If a Reactant is Solid, it being Broken down means more of the Solid will be Exposed compared to the Volume
-Particles will then have more Area to work with, so Collison's can Increase |
