Question

Which of the following changes will increase reaction rate? 
1.An increase in the concentration of reactants
2.An increase in temperature
3.Higher-energy collisions between reacting molecules

Quizplus · Accepted Answer

Increasing the concentration of reactants and the temperature will both increase the probability of collision between reactant molecules, leading to more frequent collisions and more opportunities for successful collisions to occur. Additionally, higher-energy collisions between reacting molecules, as stated in option 3, will also increase reaction rate as they result in more effective collisions with a greater likelihood of successful interaction between reacting entities. Therefore, all three options will increase the reaction rate.
