Rates Of Reaction aye Flashcards
(11 cards)
Rate of reaction = ??
Time
What is the activation energy?
The minimum amount of energy that particles must have when they collide before they react
The likelihood of a reaction relies on…
- The number of collisions
2. The amount of energy the particles have when colliding
Rate of reaction is affected by… (5 points)
- Temp of the reaction mixture
- concentration of solution
- pressure of a gas
- Surface area of a solid
- Addition of a catalyst
Describe
What’s happening
What is explain in a graph q?
Why it is happening
What does the concentration tell us?
How many particles of a solute that have dissolved in a solvent
What is the collision theory?
At a higher concentration there are more reacting particles in a given volume , this means there are more frequent collisions and hence a faster rate of reaction
How does surface area affect the rate of reaction?
There are more particles of the solid exposed to the other reaction
And therefore there will be mods successful collisions per second
What does a catalyst do??
Provides an alternate pathway that has a lower activation energy
This means there will be a higher freq of collisions
How does a catalyst help reduce costs
More product made quicker
Reusable catalyst
Less heat needed
