reaction rates

List four factors that affects the rate of a reaction

• temperature

• concentration

• surface area

• volume

• catalysts

How can you increase the concentration of a solution? (may have several correct answers)

• adding more solute

• removing some solute

• adding more solvent

• removing some solvent

Pick the TWO (2) options that will INCREASE the rate of a reaction.

• Reducing Heat

• Adding Catalyst

• Adding Heat

• Removing Catalyst

The reaction rate is _______.

• the rate at which reactants are changed into products

• the rate at which reactants are re-formed in the reverse reaction

• constant for any one chemical reaction

• impossible to measure

An object has a density of 5.2 g/ml. Determine the mass of the object by using the volume in the image and density.

• 4.16 g

• 29.12 g

• 6.5 g

• 24.96

What is the effect of increasing the temperature of a chemical reaction?

• The rate of the reaction is decreased.

• The rate of the reaction is increased.

• The reaction becomes endothermic.

• There is no effect.

To find the Volume of a material you would

• Density X Mass

• Volume X Density

• Mass ÷ Density

• Mass ÷ Volume

An increase in concentration of a solution will cause:

• Increased reaction rate

• No change

• Decreased reaction rate

If you decrease the concentration of the materials being used as reactants in a chemical reaction, what would happen to the rate of the reaction?

• the rate would decrease

• the rate would increase

• the rate would remain the same

• the reaction would stop

A reversible reaction is a chemical reaction that _______.

• can occur in both forward and reverse directions

• moves from products to reactants

• proceeds very slowly

• has a reaction arrow pointing to the left
