What happens on the molecular level when you increase the concentration of the reactants involved in the reaction?

Question

*
more particles in solution means more possible collisions between reactants
the reactant particles' speed increases so there are more collisions and increase force
having particles closer makes the reaction happen slower but way more carefully
the hotter the system is, the better the molecules can hold their orientation

Answer 1

Overall, increasing the concentration of reactants in a reaction increases the likelihood of successful collisions between reactant particles. This, in turn, increases the rate of the reaction and may lead to a higher yield of products. The increased concentration also results in a higher number of reactant particles, which can lead to more collisions and a higher chance of successful reactions occurring. Additionally, the increased concentration leads to an increase in the rate of diffusion, allowing for a more rapid mixing of reactants and facilitating the reaction process.
