Rate of reaction — practice question

Which statement about the way concentration and temperature influence the rate of a reaction is not correct?

  • AIf the concentration of a reactant is increased, the rate of reaction increases because more particles have sufficient energy to react.
  • BIf the concentration of a reactant is increased, the rate of reaction increases because there are more collisions between particles per second.
  • CIf the temperature is increased, the rate of reaction increases because there are more collisions between particles per second.
  • DIf the temperature is increased, the rate of reaction increases because more particles have sufficient energy to react.
