Why does increasing the concentration of a reactants increase the reaction rate?
Because it increases the probability of collisions
How do the factors of temperature and surface area affect the rate of chemical reactions?
Temperature affects the rate of chemical reactions by increasing the speed at which molecules move and collide, leading to more successful collisions. A larger surface area allows for more contact between reactant molecules, increasing the chance of collision and reaction. Both factors can increase reaction rates by promoting collisions between reactant molecules.
What causes the reaction rate to decrease as the reaction progresses?
The concentration of the reactants decreases.
Why does increasing connentration usually increaction rate?
Increasing concentration usually increases reaction rate because it leads to more frequent collisions between reactant molecules. This results in a higher likelihood of successful collisions, which in turn increases the rate of formation of products.
Why does the reaction decrease as the reaction progresses?
There are fewer reactants left to collide.

What happens to the reaction rate as a rectant gets used up?
As a reactant gets used up in a chemical reaction, the reaction rate generally decreases. This is because the concentration of the reactant decreases, leading to fewer collisions between reactant molecules. Consequently, the overall frequency of successful collisions diminishes, slowing down the reaction until the reactant is consumed or the reaction reaches equilibrium.
According to collision theory increasing the concentration of the reactants in a chemical reaction increases?
A.the rate of collisions between two particles.
Why does increasing connentration usually increaction rate?
Increasing concentration usually increases reaction rate because it leads to more frequent collisions between reactant molecules. This results in a higher likelihood of successful collisions, which in turn increases the rate of formation of products.
How does concentration affect rate?
Concentration affects the rate of a chemical reaction by influencing the number of reactant particles present in a given volume. Higher concentrations increase the likelihood of collisions between reactant molecules, leading to a greater frequency of effective collisions. This typically results in a faster reaction rate. Conversely, lower concentrations reduce the number of collisions, slowing the reaction.
What does higher concentration and increased pressure as means to increase reaction rate?
Higher concentration increases the number of reactant particles in a given volume, leading to more frequent collisions between them, which boosts the reaction rate. Similarly, increasing pressure, particularly for gaseous reactions, compresses the reactant molecules into a smaller volume, resulting in more collisions. Both factors enhance the likelihood of successful interactions that can lead to the formation of products, thereby accelerating the overall reaction.
Why does the reaction decrease as the reaction progresses?
There are fewer reactants left to collide.
What will happen to the number of successful collisions when the temperature increases?
When the temperature increases, the kinetic energy of the molecules in a reaction also increases. This leads to more frequent and forceful collisions between reactant molecules, resulting in a higher number of successful collisions. Consequently, the rate of the reaction typically increases, as more molecules have the necessary energy to overcome the activation energy barrier. Overall, an increase in temperature generally enhances the likelihood of successful collisions in chemical reactions.
Why does increasing concentration usually increase reaction rate?
Lncreasing the number of particles in a given volume, means they are more concentrated. Since there are more particles in a given volume it means that they will collide more often with the reacting particles. 'More often' means an increasing rate of reaction.
Why does a higher concentration make a reaction go faster?
When the concentration of a solution increases, the particles are moving quicker as they have more energy. This results in more collisions between the substrate and the solution, thus resulting in an increased rate of reaction. Even if the particles are moving at the same speed, with a higher concentration, there is a higher probability of colliding with another reactant molecule rather than a solvent molecule.
