Temperature and rate
Chemistry · Secondary 3 · Medium · Temperature and rate
Which statement about the rate of reaction is correct when the temperature of a reaction mixture is increased?
- Particles collide more frequently and with higher energy, so rate increases.
- Particles collide less frequently but with higher energy, so rate stays the same.
- Particles collide more frequently but with lower energy, so rate decreases.
- Neither collision frequency nor energy changes, so rate is unchanged.
