Reactions

• What is an Endothermic reaction?

  A reaction that takes in energy from the surroundings, so the temperature of the surroundings decrease.
• What is an Exothermic reaction?

  A reaction that transfers energy to the surroundings. The temperature of the surroundings increase.
• What is Activation energy?

  The minimum amount of energy needed for a successful collision.
• Draw an energy profile for exothermic reactions.

  Will decrease

  
• Draw an energy profile for endothermic reactions.

  Will increase
