Rates graphs: zero, first and second order

Question 1

What does a conc time graph look like for 0 order?

Answer 1

= straight line going down
= doubling the concentration, the affect on rate is no effect

Question 2

What does a conc time graph look like for first order?

Answer 2

= a curve going downwards
= this does not touch the x-axis
= doubling the concentration, the rate doubles

Question 3

What does a conc time graph look like for 2nd order?

Answer 3

= curve downwards, but touches axis and steeper
= 2nd order
= double concentration, the rate quadruple (2^2)

Question 4

What does rate concentration graph looks like?

Answer 4

= flat
= gradient is the same, constant

Question 5

What does the rate concentration graph look like for first order?

Answer 5

= a straight line going through the origin

Question 6

What does the rate concentration graph look like for 2nd order?

Answer 6

= curve going upwatds
