How does an increase in reactant concentration affect the rate of reaction?
It leads to more frequent collisions, which increase reaction rate.
Why does an increase in reaction temp generally increase the reaction rate?
the umber of collisions increases
What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
Does a increase in pressure cause an increase of reaction rate?
Yes
What causes an increase in the rate of a chemical reaction between 2 liquids?
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
Why does grinding a solid into powder increase reaction rate?
Increased surface area for reaction to occur on
Not increase the rate at Which a solid dissolves?
Decreasing temperature would not increase the rate at which a solid dissolves
What are three ways to increase the rate at which particular reaction proceeds?
There are three ways to increase the rate of a chemical reaction. One way is to increase the temperature of the reaction, which increases the rate of molecular collision. Another option is to add a catalyst to the reaction which chemically enables the rate of reaction. Lastly, increase the pressure in the reaction area, which increases the rate of molecular collisions.
What leads to an increase in the rate of a chemical reaction?
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
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 is the effect of concentration changes on the reaction seen in the rate law?
Reaction rate increase when the concentration increase.
Would not increase the rate at which a solid dissolves?
Decreasing temperature would not increase the rate at which a solid dissolves
An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.
How does an increase in reactant concentration affect the rate of reaction?
It leads to more frequent collisions, which increase reaction rate.
How does heat affect the rate of the reaction?
Increasing the temperature the reaction rate increase.
What does temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
Why is the solution boiled after adding excess hydrochloric acid to the solid hydrate?
to remove carbondioxide from the solution and also to increase the rate of reaction
