Total questions: 9
Worksheet time: 10mins
Grinding a solid into fine particles (ex: sugar granules)
Increases rate of reaction
Decreases rate of reaction
Leaving a solid in one large block (Ex: Sugar cube)
Increases rate of reaction
Decreases rate of reaction
Increasing the temperature will
Increase rate of reaction
Decrease rate of reaction
Decreasing pressure, allowing particles to move with more space (the 1st container has a decreased pressure) will...
Increase rate of reaction
Decrease rate of reaction
Changing the concentration of the particles from 80% to 40% will
Increase rate of reaction
Decrease rate of reaction
Adding a catalyst to the reactants will
Increase rate of reaction
Decrease rate of reaction
Fill in the blank with the correct words:
A catalyst ___________ the rate of reaction by _________ the activation energy.
Increases; increasing
Increases; decreasing
Decreases; decreasing
Decreases; increasing
In order for a chemical reaction to occur, there must always be... (select all that apply)
a bond that breaks in a reactant particle
reacting particles with a high charge
an effective collision between reacting particles
enough energy
Analyze the table below and select the statement that best explains the change that occurs.
Due to an increase in temperature from trial 1 to trial 2, the rate of reaction was faster because the color change took less time
Due to an decrease in temperature from trial 1 to trial 2, the rate of reaction was faster because the color change took less time
Due to an decrease in temperature from trial 1 to trial 2, the rate of reaction was faster because the color change took more time
