Science- Activation Energy

Question 1

energy needs for a reaction to take place

Answer 1

heat of reaction

Question 2

made up of unstable + unbonded atoms

Answer 2

activated complex

Question 3

increases activation energy, takes more energy to take place, slows down reaction

Answer 3

inhibitor

Question 4

activation energy

Answer 4

least amount of energy needed for a reaction to take place

Question 5

effective collision

Answer 5

enough energy to break a bond

Question 6

speeds up reactant, gives more energy to system, lowers activation energy

Answer 6

calalyst

Question 7

how do you calculate the heat of a reaction?

Answer 7

heat of rxn = product - reactant

Question 8

endothermic reaction:

Answer 8

+ heat of rxn, nonspontaneous, energy will be a reactant, feels cold, takes in energy, energy of rxn < energy of product

Question 9

how do you calculate the activation energy?

Answer 9

activated complex = activated complex - reactant

Question 10

exothermic reaction:

Answer 10

heat of rxn + spontaneous, energy will be a product, feels hot, releases energy, energy of rxn > energy of product
