Increasing the concentration of the acid raises the rate of reaction between magnesium and dilute hydrochloric acid. What effect does this have on 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
