Rates of Reaction

What is Rate of Reaction?

The rate of reaction tells us how fast reactants change into products.

Factors That Affect Rate

• Temperature: higher temperature speeds up reactions.
• Concentration: more concentrated solutions react faster.
• Surface area: smaller pieces react faster than large lumps.
• Catalyst: speeds up a reaction without being used up.

Key Points

Reactions go faster when particles collide more often and with more energy.
