TABLE 6.4 Flashcards
Factors That Affect the Rate of a Reaction
1
Q
EFFECT of concentration of reactions
-Raising the concentration….
-Why?
A
-increases the reaction rate
-Reactant molecules collide more frequently
2
Q
EFFECT of surface area of solids and liquids
-Stirring and breaking up solids….
-Why?
A
-increases the reaction rate
-the surface area is increased, exposing more reactant molecules
3
Q
EFFECT of temperature
-Raising the temperature…
-Why?
A
-Increases the reaction rate
-more molecules have enough energy to react (activation energy)
4
Q
EFFECT of a catalyst
-Adding a catalyst…
-Why?
A
-Increases the reaction rate
-The catalyst lowers the activation energy
