What factors increases the reaction rate by increasing particle speed?
Increasing the temperature of the system leads to higher particle speeds, increasing the chances of collisions between reactant molecules. This in turn increases the reaction rate as a higher proportion of collisions will have sufficient energy to overcome the activation energy barrier.
What effect does raising the temperature have on the speed of reaction for the forward reaction and why?
In general, but not always, increasing the temperature will increase the rate of the forward reaction. This is because an increase in temperature increases the speed at which the molecules move, increasing the kinetic energy, and thus making it easier to reach the activation energy. Of course, this is true only for endothermic reactions. If the reaction is exothermic, then increasing the temperature will slow down the forward reaction.
As the temperature of a chemical reaction in the gas phase is increased the rate of the reaction increases because?
Increasing the temperature of a chemical reaction in the gas phase leads to an increase in the kinetic energy of the molecules, resulting in more frequent and energetic collisions. This enhances the likelihood of successful collisions that lead to product formation, thus increasing the reaction rate. Additionally, higher temperatures can lower the activation energy barrier for the reaction, making it easier for the reaction to proceed.
How does increasing the temperature effect a chemical reaction?
Increasing the temperature usually increases the rate of a chemical reaction by providing more energy to the reacting molecules. This allows the molecules to collide more frequently and with greater energy, leading to more successful reactions occurring per unit time. However, very high temperatures can also denature proteins or break chemical bonds, inhibiting the reaction.
How increasing the concentration of Potassium iodide and Sulfuric acid affects the speed of reaction?
Increasing the concentration of Potassium iodide and Sulfuric acid typically increases the rate of reaction. This is because higher concentrations provide more reactant particles, leading to more frequent collisions and a higher likelihood of successful collisions, which speeds up the reaction.

How is heat involved in chemical changes?
Heat increases the speed at which the molecules move, thus increasing the speed of the reaction.
How does average particle speed affect the reaction rate?
As the speed of the particles increase, it causes them to collide with the other particles in which they are reacting with more frequently, increasing the reaction rate.
What happens to the energy of a particle if the mass is constant and the speed increases?
The kinetic energy of the particle increases as the speed increases, following the equation ( KE = \frac{1}{2} mv^2 ) where ( KE ) is the kinetic energy, ( m ) is the mass of the particle, and ( v ) is the speed of the particle. The energy of the particle is converted to kinetic energy as its speed increases.
What speeds up chemical reactions?
to speed up a chemical reaction .. we use a catalyst

If you add heat energy to a substance what happens to the speed of the particle motion?
The particle speed increases.The energy increases; the speed increases.
Why does the rate of a reaction speed up?
Catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction (or the rate of the reaction) increases.
What do you decrease to speed up a chemical reaction?
Particle size

Is it that reaction distance increases with speed while the reaction time stays the same?
Yes, the reaction distances increases with speed while reaction time stays the same. for example the two-second rule.
Why does reducing solute particle size increase the speed at which the solute dissolves water?
As the particle size gets smaller, the surface area increases, and as the surface area increases, the ease with which water can hydrate the particles increases. When it is easier for water to hydrate the molecules, this increases the speed at which the solute dissolves.
