What increase is the chance of a reaction when two molecules collide?
pressure
What would increase the chance of a reaction when two molecules collide?
The most important is the activation energy.
According to kinetic and collision theory why does increasing the temperature of the reaction increase the rate of reaction?
The likelihood that two particles will collide in a given time increases. The number of particles per volume increases.
What changes of temperature on rate of reaction?
The rate of reaction increases with increasing temperature. When the temperature is increased, the kinetic energy of the reacting particles hence the frequency of effective collisions are also increased. Hence the rate of reaction is faster.
What is the main advantage of using a warm solution over a cold solution in a chemical reaction?
When solutions are heated, molecules are excited and speed up. This increases the chance that they will "bump" into each other and react, thus increasing the reaction rate. Also, many reactions require a certain Activation energy in the form of heat to even start the reaction.

What can increase the chance of a reaction when two molecules collide?
An increase in the temperature usually increases the rate of reaction by increasing the number of collisions.

What is a main reason that an increase in temperature increases the rate of a chemical reaction?
Temperature is the measure of the average kinetic energy of the molecules involved. If the temperature increases, then the kinetic energy of the molecules increases and they move faster. Faster moving molecules have more collisions with other molecules and more forcefully. For a reaction to occur, the molecules have to line up correctly and with adequate force. By increasing the speed of the particles, you are increasing the chance that the two molecules will align and produce a reaction.
What changes of temperature on rate of reaction?
The rate of reaction increases with increasing temperature. When the temperature is increased, the kinetic energy of the reacting particles hence the frequency of effective collisions are also increased. Hence the rate of reaction is faster.
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:ConcentrationNature of reactantsTemperatureCatalystsFor 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.
What happens to the rate constant of a chemical reaction when the temperature increases?
Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.
How does the factor concentration affect reaction rate?
increasing concentration increases rate of reaction as there are more particles so there is a larger chance of collision,it increases the probability of collision of the reactants.
