Rate of reaction — practice question

Which row states the effects of raising both concentration and temperature on collisions between reacting particles?

  • Aincreasing concentration: more collisions per second only; increasing temperature: more collisions per second only
  • Bincreasing concentration: more collisions per second and more collisions with sufficient energy to react; increasing temperature: more collisions per second only
  • Cincreasing concentration: more collisions per second only; increasing temperature: more collisions per second and more collisions with sufficient energy to react
  • Dincreasing concentration: more collisions per second and more collisions with sufficient energy to react; increasing temperature: more collisions per second and more collisions with sufficient energy to react
