Rate of Reaction

Question 1

List some methods for measuring RoR

Question 2

Definition of RoR

Answer 2

The measure of how quickly and readily and substance is used up

Question 3

What is concentration and how does it effect RoR

Answer 3

Cocentration is the measurement of how many particles of a substance is in a certain volume of eg. water
An increase of concentration is an increase number of particles in a certain volume therefore if the particles are increased theres an increase in number of sucessful collisons

Question 4

What is tempurature and how does it effect RoR

Answer 4

Measure of how much knetic energy there is
increase knetic energy increase chne of collison increse rate of reaction

Question 5

What is the Surface Area and how does it affect RoR

Question 6

What is a Catalyst and how does it affect RoR

Question 7

The four factors that affect RoR are:

Question 8

Key aspects of collision theory:

Question 9

Definition of Activation Energy:

Question 10

Formula to calculate Activation energy:

Question 11

Definiton of and signs for exothermic reaction:

Answer 11

Exothermic reactions give out energy therefore on an energy level diagram the reactants are above the products

Question 12

Formula to calculate Overall energy change:

Question 13

Definition and sign for endothermic reactions

Answer 13

endothermic reactions absorb energy
Therefore on an energy level diagram reactants are
