Rate Of Reaction Flashcards
What is the definition of the rate of reaction?
The rate of reaction is the speed at which reactants are converted into products in a chemical reaction.
True or False: The rate of reaction can be influenced by temperature.
True
Fill in the blank: The rate of reaction is typically measured in __________.
moles per liter per second (mol/L/s)
Which factor does NOT affect the rate of reaction?
The color of the reactants.
What effect does increasing the concentration of reactants have on the rate of reaction?
It generally increases the rate of reaction.
Name one physical state of reactants that can affect the rate of reaction.
Solid, liquid, or gas.
What is the effect of temperature on the rate of reaction?
Increasing temperature usually increases the rate of reaction.
True or False: Catalysts increase the rate of reaction without being consumed in the process.
True
What role does surface area play in the rate of reaction?
Increased surface area leads to a higher rate of reaction.
How does pressure affect the rate of reaction for gases?
Increasing pressure increases the rate of reaction by forcing gas molecules closer together.
What is a catalyst?
A substance that increases the rate of a chemical reaction without undergoing permanent change itself.
Multiple choice: Which of the following factors can affect the rate of reaction? A) Temperature B) Surface Area C) Concentration D) All of the above
D) All of the above
What is the relationship between reaction rate and activation energy?
A lower activation energy typically results in a higher reaction rate.
Fill in the blank: The __________ theory explains how temperature affects the rate of reaction.
collision
What happens to the rate of reaction as the reactants are consumed?
The rate of reaction generally decreases as reactants are consumed.
