An increase in the concentration of the reactants of a reaction leads to change in:
A
heat of reaction
B
threshold energy
C
collision frequency
D
activation energy
Detailed Solution
The number of collisions per second per unit volume of the reaction mixture is the collision frequency.
Increasing the concentration of reactants increases the number of molecules per unit volume, so the collision frequency changes (increases).
Heat of reaction, threshold energy and activation energy do not depend on concentration.
