Reaction Rate and Factors Affecting it
This makes reactions happen faster because particles move quicker.
What is temperature?
Particles must do this for a reaction to happen.
What is collide?
Scientists often use this tool to measure reaction time.
What is a stopwatch?
Enzymes are natural__.
What are catalysts?
Acids have a pH lower than this number.
What is 7?
Breaking something into smaller pieces increases this.
What is surface area?
Collisions need enough of this to react.
What is energy?
Gas bubbles can show how fast a reaction is happening.
What is measuring gas production?
Enzymes work best at certain temperature and __.
What is pH?
Bases have a pH higher than this number.
What is 7?
More particles in the same space means a higher__.
What is concentration?
A collision that causes a reaction is called this.
What is an effective collision?
When a liquid gets cloudy, it can mean this is forming.
What is precipitate?
The thing an enzyme works on is called a __.
What is a substrate?
Magnesium reacting with hydrochloric acid makes this gas.
What is hydrogen gas?
A reaction that happens quickly has a fast__.
What is reaction rate?
Food spoils faster in warm temperature because particles move faster.
What is collision theory?
The faster products from, the faster the __.
What is reaction rate?
High heat can change the shape of an enzyme. This is called__.
What is denatured?
Antacids help by lowering stomach acid.
What is neutralizing acid>
Food cooks faster in a pressure cooker because pressure increases the reaction rate.
What is pressure?
Fire burns faster when oxygen is added because there are more particles collisions.
What is collision theory?
One way to measure a reaction is by recording the change in this over time.
What is mass?
Enzymes help reactions happen faster in living things.
What are enzymes?
Increasing the concentration of an acid usually makes the reaction happen faster.
What is a faster reaction rate?
