Question
Which would lower the reaction rate?A.Increasing the temperature of the systemB.Increasing the concentration of reactantsC.Raising the value of kD.Decreasing the temperature of the system
Solution
D. Decreasing the temperature of the system
Here's why:
A. Increasing the temperature of the system would actually increase the reaction rate. This is because higher temperatures provide more energy to the molecules involved in the reaction, which makes them move faster and collide more often and with greater energy.
B. Increasing the concentration of reactants would also increase the reaction rate. More molecules of reactants mean more collisions and therefore a faster reaction.
C. Raising the value of k (the rate constant) would increase the reaction rate. The rate constant is directly proportional to the reaction rate, so if k increases, the reaction rate also increases.
D. Decreasing the temperature of the system would lower the reaction rate. Lower temperatures mean less energy for the molecules, so they move slower and collide less often and with less energy. This results in a slower reaction rate.
