  • Catalysts
  • Factors
HideShow resource information
How do more collisions affect the rate of reaction?
It increases it. Partices have to collide hard enough with enough energy to react.
1 of 6
How does a higher temperature affect the rate of reaction?
It increases the collisions. The particles move quicker so they'll collide more often.
2 of 6
How does a higher cencentration affect the rate of reaction?
It increases the collisions. There are more particles so collisions are more likely.
3 of 6
How does a larger surface area affect the rate of reaction?
It increases the collisions. There is more area to work on so the particles have a greater chance to collide with.
4 of 6
What is a catalyst?
A catalyst is a substance which speeds up a reaction, without being changed or used up in the reaction.
5 of 6
How do catalysts reduce costs in industrial reactions?
The plant doesn't have to run as long.
