Because it increases the probability of collisions

∙ 12y agowhen you increase the concentration of the reactants the particles move quicker resulting in more collision. This makes the rate of the reaction to increase.
Even if the particles are moving at the same speed, with a higher concentration of reactants, there is a higher probability that a reactant molecule will collide with another reactant molecule rather than with a water molecule.

How does increasing pressure affect the reaction rate?
The concentration of reactants is changed.
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
What is rate dependence on concentration of reactants?
The reaction rate increase with reactants concentration.
What would increase the reaction rate?
raising the temperature of the reactants, by increasing their surface area, by increasing the concentration of reactants, by stirring the reactants, or by adding a catalytic agent can increase reaction rates
Name two ways to speed up a reaction?
increasing surface area addition of a catalyst

What is the effect varying the concentration on the rate of reaction time?
Increasing the concentration of the reactants the rate of reaction increase.
How does increasing pressure affect the reaction rate?

TO INCrease the rate of a reaction why would you increase the concentration of the reactants?
For most reactions which involve liquids or gases, increasing the concentration of the reactants also increases the rate of reaction. This is because the number of effective collisions are also increased which speeds up the reaction.

When Increasing the concentration and increasing the temp both increase the reaction rates based on which physical phenomenon?
The kinetic energy of the reactants. By increasing the concentration, there are more reactant particles available for the reaction, and increasing the temperature increases the kinetic energy so the reactants come in contact more often, and the reaction rate increases.
What is rate dependence on concentration of reactants?
The reaction rate increase with reactants concentration.
What effect does the concentration on reactants have on the rate of a reaction?
