Which would lower the reaction rate?
A. Increasing the concentration of reactants
B. Raising the value of k
C. Decreasing the temperature of the system
D. Increasing the temperature of the system
Answer (2)
Decreasing the temperature of the system would lower the reaction rate because it reduces the kinetic energy of the molecules, leading to fewer effective collisions. In contrast, increasing concentrations or temperature can raise the rate of reaction. The correct answer is option C. ;
Decreasing the temperature of the system will lower the reaction rate as it reduces kinetic energy, leading to fewer effective collisions between molecules. Therefore, the correct answer is option C.
