Endothermic and Exothermic Reactions

Question 1

What is a Exothermic Reaction

Answer 1

Is a reaction which gives out energy to the surrounding. This is usually in the form of heat and shown by the rise in temperature

Question 2

What is a Endothermic Reaction

Answer 2

A endothermic reaction is one which takes in energy from the surroundings, usually in the form of heat. This shows a decrease in temperature

Question 3

What does this show?

Answer 3

This shows an exothermic reaction. The products have a lower energy than the reactants. The difference in height is the energy given out

Question 4

What does this show

Answer 4

This shows an endothermic reaction. The products are at a higher energy than the reactants. The difference in height is the energy taken in.

Question 5

What is the activation energy

Answer 5

The is the minimum amount of energy needed for bonds to break

Question 6

what does this show?

Answer 6

This is the reaction profile. The activation energy is a the difference between the reactants and the highest point on the graph.
