Sagot :
When we increase the concentration of a reactant in a chemical reaction, we are essentially adding more particles of the reactant into the system.
Here is a detailed step-by-step explanation:
1. Understanding Collision Theory: According to the Collision Theory of chemical reactions, for a reaction to occur, the reacting particles must collide with sufficient energy and proper orientation. This energy is known as the activation energy.
2. Effect of Concentration on Collisions: When we increase the concentration of a reactant, the number of particles per unit volume increases.
3. Frequency of Collisions: As a result of the increased number of particles, the likelihood of reactant particles colliding with each other also increases.
4. Conclusion: Therefore, increasing the concentration of a reactant leads to an increase in the frequency of collisions between the reactant particles.
Based on this understanding:
Correct Option:
A) There are more collisions.
This matches our true answer, where an increase in concentration results in more collisions between particles.
