Question 1

what are the factors that can be measured to determine rate of reaction

Answer 1

-mass last by regent
- mass gained by product
- volume of gas
- pressure of gas
- colour intensity
- solution concentration
- ph

Question 2

define collision theory

Answer 2

states correct particle orientation and sufficient energy are the two vital factors which must be met for a successful collision.

Question 3

what is a Maxwell Boltzmann distribution

Answer 3

a curve showing the kenetic energy of all particles in a substance and the number of particles which surpass the activation energy needed for reaction to occur. number of particles on the y-axis and energy on the x-axis

Question 4

what is an energy profile diagram

Answer 4

shows the energy needed for a reaction to occur, and the energy throughout the course of the reaction. (energy of reactants and energy of products). can determine if a reaction is endothermic (higher energy in products) or exothermic (higher energy in reactants)

Question 5

what factors influence rate of reaction

Answer 5

surface area - more collisions
pressure - more collisions
concentration - more collisions
temperature - more successful collisions
catalysts - more successful collisions

Question 6

what is the limiting reagent

Answer 6

the reagents which stops the reaction from proceeding.
