Reaction profiles

Question 1

is bond breaking endothermic or exothermic

Answer 1

endothermic

Question 2

why is breaking bonds endothermic

Answer 2

energy has to be supplied to break bonds

Question 3

is making new bonds endothermic or exothermic

Answer 3

exothermic

Question 4

why is making bonds exothermic

Answer 4

because it transferred energy to the surroundings

Question 5

what is activation energy

Answer 5

minimum energy required before colliding particles of reactants have sufficient energy to cause a reaction

Question 6

explain how reaction profiles show how the reaction is exothermic

Answer 6

because the arrow goes down, it shows that the energy in the reactants is more than the products, this is because energy is released therefore its no longer in the products

Question 7

explain how reaction profiles show how the reaction is endothermic

Answer 7

the products are at a higher energy level than the reactants. this is because energy is taken in, therefore taking in more energy to the products, meaning the surrounding temp decreases
