Reactions Flashcards
What does exothermic do?
Transfer heat into the surroundings
Name two types of heat reactions.
Endothermic and exothermic
What does endothermic do?
Transfers heat from the surroundings
Give an example of exothermic.
Combustion or respiration
Give an example of endothermic.
Photosynthesis and thermal decomposition
How can the reaction rate be increased?
Increasing temperature, increasing concentration and decreasing surface area.
Using what method also speeds up reaction?
Using a catalyst.
Why does decreasing surface area increase reaction rage?
Particles collide more often
What are the disadvantages for using a catalyst?
Expensive, different catalyst required for different reactions and can be poisoned.
How can we tell if it is an exothermic reaction?
Temperature increases
How can we tell if it is a endothermic reaction?
Temperature decreases
