The rate of reaction between magnesium and dilute hydrochloric acid is increased when the acid concentration is raised. How does this affect the reacting particles?
- Acollision rate of particles increases; proportion of particles with sufficient energy to react increases
- Bcollision rate of particles increases; proportion of particles with sufficient energy to react stays the same
- Ccollision rate of particles stays the same; proportion of particles with sufficient energy to react increases
- Dcollision rate of particles stays the same; proportion of particles with sufficient energy to react stays the same
