Reaction kinetics — practice question

If the temperature of a particular reaction is raised by $10\,^{\circ}\text{C}$ (for example, from $20\,^{\circ}\text{C}$ to $30\,^{\circ}\text{C}$), the reaction rate roughly doubles. Which is the main explanation for this increase?

  • Aa different mechanism for the reaction
  • Ban increased collision frequency of the reactant molecules
  • Cmore collisions have energy greater than the activation energy
  • Da reduced activation energy for the reaction
