U1 Rates of Reaction Flashcards
1
Q
What are the four ways a chemical reaction can be sped up?
A
Catalyst
Temperature
Concentration
Particle Size
2
Q
What is a catalyst
A
A substance that can speed up a chemical reaction while remaining unchanged
3
Q
How does a decrease in particle size speed up reactions
A
Created a larger surface area
4
Q
How does an increase in temperature allow for higher reaction rate
A
Makes the particles move faster and meet activation energy more frequently
5
Q
How does increase in concentration resulting in faster reaction speed
A
There are more particles in the solution to collide with
