Why does increasing the pressure or concentration increase the rate of reaction?

Keep in mind that the reaction can only occur if the particles collide with enough power in the right position.
The rate of reaction generally depends on four factors:
- Concentration
- Nature of reactants
- Temperature
- Catalysts
For gases, pressure is also a factor. Say we have 1L of a gas and we compress it to 0.5L. Decreasing the volume will increase the pressure, and with a lower volume with the same number of particles increases the molarity (M). And as a convention, increasing the molarity/concentration increases the rate of the reaction because there is more of a chance for particles to collide in a small space rather than in a large space.
Temperature also increases the rate of the reaction because it increases the kinetic energy of the particles, which will mean that more particles have the energy equal to or above the activation energy for the reaction to occur.

How does increasing pressure affect the reaction rate?
The concentration of reactants is changed.
Will Increasing the rate at which particles collide will increase the rate of a reaction?
Yes. For this reason, increasing the concentration of the molecules involved increases the rate of reaction.
Name two ways to speed up a reaction?
increasing surface area addition of a catalyst
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
What change will most likely increase the rate of a chemical reaction?
Factors which can increase the rate of a chemical reaction:- temperature- pressure- concentration of reactants- stirring- if solids are involved the dimension of particles is important- the type of reaction- the order of reaction- presence of catalysts- influence of external factorsetc.
How does increasing pressure affect the reaction rate?
The concentration of reactants is changed.
What is the effect varying the concentration on the rate of reaction time?
Increasing the concentration of the reactants the rate of reaction increase.
What is the effect of increasing the concentration of enzymes in a reaction?
If the reaction speed has not already peaked, then it will increase
How do concentration affect rate?
Increasing the concentraion the reaction rate increase.
Does increasing concentration increase the rate of reaction?
increasing the concentration in a rate of reaction makes the reaction take place faster because if there is more initial particles then there is more particles to react
Will Increasing the rate at which particles collide will increase the rate of a reaction?
Yes. For this reason, increasing the concentration of the molecules involved increases the rate of reaction.

How might you increase the reaction rate between calcium carbonate and acid?
Possible actions:- stirring- heating- increase of the acid concentration- fine grinding of calcium carbonate- increasing the pressure
Does increasing pressure affect reaction rate?
If the pressure increase the number of intermolecular collisions increase and so the reaction rate. This is valid for gases.
What would increase 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
What is a good chemical reaction to prove that increasing concentration will increase the rate of reaction?
hydrochloric acid and sodium thiosulfate Google it.
Why does increasing the pressure of a gas increase the reaction time?
The explanation is: increasing the pressure is equal to an increasing of concentration of reactants.In a concentrated environment the possibility of interactions between molecules is higher.And the consequence of more collisions is the increasing of reaction rate.
