I WONDER - How Fast Do Chemical Reactions Occur?

Chemical reactions occur at different speeds, influenced by factors like temperature, reactant amounts, and stirring. Quick reactions include glow sticks snapping and soda fizzing, while slow reactions include rusting and tree growth. Lower temperatures, such as in a fridge, slow down reactions, delaying spoilage.

Which of the following is an example of a fast chemical reaction?

• The snap of a glow stick

• A tree growing

• Food spoiling in a fridge

• Rust forming on metal

What is an example of a slow chemical reaction?

• The fizz when you open a soda

• A match burning

• Rust forming on metal

• The snap of a glow stick

What is one factor that can influence the speed of a chemical reaction?

• The time of day

• The color of the reactants

• The temperature

• The shape of the container

How does stirring affect the speed of a chemical reaction?

• It slows down the reaction

• It changes the color of the reactants

• It has no effect

• It speeds up the reaction

Why does food spoil more slowly in a refrigerator?

• Because of the high humidity

• Due to the low temperature

• Because of the lack of light

• Due to the presence of preservatives
