Rate of reaction — practice question

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
