An increase in the concentration of the reactants of reaction leads to change in:
An increase in the concentration of the reactants of reaction leads to change in:
The correct option is C Collision frequency
Explanation of the correct option:
(c) Collision frequency: The number of collisions per second per unit volume of the reaction mixture is known as the collision frequency.
- As the concentration of the reactants increases, the number of reactant molecules per unit volume increases increasing the collision frequency and resulting in the formation of products.
Explanation of the incorrect options:
(a) Heat of reaction: Heat of a chemical reaction is the heat evolved in the surroundings or absorbed when the reaction takes place at constant pressure and temperature.
(b) Threshold energy: The minimum amount of energy that colliding molecules must possess for the collision to be effective and result in a chemical reaction.
(d) Activation energy: Activation energy is the minimum amount of extra energy required by a reacting molecule to get converted into product.
Hence, option (c) is correct.
