Kinetics

Question 1

when do reactions occur

Answer 1

when a succesful collision occurs

Question 2

what is activation energy

Answer 2

minimum amount of energy required for a successful collision

Question 3

what does a maxwell-boltzmann distribution look like

Answer 3

y axis - number of particles
x axis - kinetic energy
goes up then slants downwards doesnt touch origin

Question 4

effect of temperature on maxwell boltzmann distribution

Answer 4

lowers peak and moves to right

Question 5

effect of temperature increase on rate of reaction

Answer 5

increases rate of reaction as more particles have energy equal to or greater than activation energy
as they have greater kinetic energy

Question 6

what is rate of reaction

Question 7

effect of conc and/or pressure increase on rate of reaction

Answer 7

increase will cause more molecules to occupy the same volume meaning there are more closely packed therefor more frequent collisions so rate of reaction increases

Question 8

effect of a catalyst on rate of reaction

Answer 8

increases rate of reaction by providing an alternative route of lower activation energy
increase in rate of reaction as more particles will have energy equal to or greater than the new lower activation energy
