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:
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.
The concentration of reactants is changed.
Yes. For this reason, increasing the concentration of the molecules involved increases the rate of reaction.
increasing surface area addition of a catalyst
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
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.
The concentration of reactants is changed.
Increasing the concentration of the reactants the rate of reaction increase.
If the reaction speed has not already peaked, then it will increase
Increasing the concentraion the reaction rate increase.
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
Yes. For this reason, increasing the concentration of the molecules involved increases the rate of reaction.
increasing surface area addition of a catalyst
Possible actions:- stirring- heating- increase of the acid concentration- fine grinding of calcium carbonate- increasing the pressure
If the pressure increase the number of intermolecular collisions increase and so the reaction rate. This is valid for gases.
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
hydrochloric acid and sodium thiosulfate Google it.
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.
