List four factors that affects the rate of a reaction

• temperature

• concentration

• surface area

• volume

• catalysts

How does a catalyst work in speeding up a reaction?

• By lowering the activation energy or reaction

• by giving them more energy

• by making them more available

Why does a higher concentration increase the rate of reaction?

• it increases the amount of reactants

• it lowers the activation energy

• it increases the energy of particle collisions

• it increases the frequency of particle collisions

The ______________is required to break the bonds of the reactants.

• Carbonic energy

• Activation energy

• Plutonic energy

• Energi Gaib

In class, we completed a foam animal lab to see if water temperature had an effect on the time it took for the foam animal to form.

What was the dependent variable?

• The temperature of the water

• The type of foam animal

• The amount of time it took for the animal to form

• The type of cup/beaker used

Cindy wanted to find out how the amount of sunlight affects the growth of plants. She placed two tomato plants in 10 inch pots with potting soil and watered them ¼ cup each day. One plant was placed under a cardboard box and one was placed in the sunlight. She measured the growth of the plant each week for three weeks.

What is the independent variable?

• Using the same type of plant

• The growth of the plant

• Each plant was placed in a 10 inch pot

• One plant is in the sunlight and the other is under a box
