The rate of a reaction usually increases with increase in the concentration of reactants because the

a

distance between particles of the reactants increases

b

frequency of collision of particles is lower

c

particles of the reactants gain energy and move faster

d

reactants from a complex which decomposes rapidly

e

reactants occupy a higher energy level

The answer should be C

@Myschool the selected option picked is wrong the correct answer is option c
The correct answer is C. particles of the reactants gain energy and move faster.

Increasing the concentration of reactants means there are more particles present in a given space. This leads to a higher frequency of collisions between reactant particles, and as a result, the particles gain energy and move faster. This increases the likelihood of successful collisions that can lead to the formation of products, thereby speeding up the reaction rate.

Myschool, the answer is C.
Orthereshould ve no answer
Increasing concentration cannot form a complex ion

Increasing concentration makes particles interact more often (more collisions), so the reaction happens faster — and D is the closest option to that idea. Temperature is what affects energy of particles not concentration

Myschcool could you pls correct this answer you gave ,it is C not D,and if you feel C is wrong kindly explain why D is correct.

No total accurate answer which supposed to be increase in frequency of collision, but option C could be accepted in this case.

The correct answer is:

C. Particles of the reactants gain energy and move faster

Explanation:
An increase in the concentration of reactants leads to a higher number of reactant particles per unit volume, which increases the frequency of collisions between particles. More frequent and energetic collisions mean that more particles have the required activation energy, leading to a faster reaction rate.
