1765 - What are the factors that affect the reaction rate according to collision theory?

According to collision theory, there are four main factors that affect the reaction rate:

1. Concentration: More particles (like molecules or atoms) mean more collisions, so the reaction goes faster.
2. Temperature: Higher temperatures give particles more energy to move and collide, making the reaction faster.
3. Surface Area: A larger surface area gives more space for particles to collide and react, so reactions go faster.
4. Particle Speed and Direction: If particles are moving in the right direction and have enough energy (speed), they're more likely to collide and react.

Think of it like a big party. More people (particles), hotter music (temperature), a bigger dance floor (surface area), and people dancing in sync (speed and direction) all make the party more exciting (reaction rate faster)!
