Chapter 7 - Rate of Chemical Reactions

Question 1

factors that affect reaction rates

Answer 1

surface area.
concentration of reactants.
gas pressure.
temperature.
catalysts

Question 2

rate of reaction

Answer 2

speed at which the reaction happens

Question 3

collision theory

Answer 3

for a reaction to occur, the reactants must collide with:
each other.
sufficient energy to break bonds.
correct orientation

Question 4

activation energy

Answer 4

minimum amount of energy that collision must possess for reaction to occur

Question 5

transition state

Answer 5

unstable arrangement of atoms in reaction that occurs when sufficient energy is absorbed for activation energy to be reached

Question 6

you can increase the proportion of successful collisions by…

Answer 6

increasing frequency of successful collisions by increasing number of collisions.
increasing proportion of collisions that have energy equal to or greater than activation energy

Question 7

maxwell-boltzmann distribution curve

Answer 7

graph of kinetic energy against number of particles that shows range of energy in a sample at given temperature
