Question

An increase in the concentration of the reactants of a reaction leads to change in ______.

Options

• activation energy

• heat of reaction

• threshold energy

• collision frequency

Answer 1

An increase in the concentration of the reactants of a reaction leads to change in collision frequency.

Explanation:

Increasing the concentration of reactants leads to an increase in the number of reactant particles per unit volume. This results in a higher collision frequency, i.e., more frequent collisions among particles, thereby potentially increasing the reaction rate. However, activation energy, threshold energy, and heat of reaction remain unchanged.
