chemical kinetics definitions

Question 1

activation energy

Answer 1

the minimum amount of energy a reaction entity must possess for a reaction to be successful

Question 2

activation complex

Answer 2

unstable arrangement of atoms that contain partially formed and unformed bonds

Question 3

5 basic factors

Answer 3

chemical nature, concentration, surface area, temperature, catalysts

Question 4

collision theory

Answer 4

states that chemical reactions can only occur if reactants collide with proper orientation and with enough kinetic energy to break reactant bonds and form product bonds

Question 5

weaker vs. stronger bonds

Answer 5

less activation energy is needed to break weaker bonds

Question 6

complex molecules

Answer 6

complex molecules contain more bonds, must be broken and in proper orientation

Question 7

number of bonds per reactant

Answer 7

breaking fewer bonds per reactant allows the reaction to proceed faster

Question 8

molecules vs. ions

Answer 8

molecules contain covalent bonds which have to be broken so new bonds can form
