Mathematical relationship between reaction time and reaction rate HELP

[lanfear]

Homework Statement

I am writing a report for an Iodine clock lab, the questions I am having trouble with are:

1.What mathematical relationship exists between reaction rate and reaction time?

2.What mathematical relationship exists between concentration and reaction time?

3.What mathematical relationship exists between concentration and reciprocal of time?

The Attempt at a Solution

I am pretty sure that the answer for question 2 is r=k[A]nm. I know that when reaction rate increases then reaction time decreases, but I am not sure how I should be expressing that. Is the answer for number one the same as number two? I am totally at a loss for number 3. HELP!

2 is not r=k[A]nm because r is reaction rate, not reaction time.

For number 1), what's the relationship between speed and the time needed to travel 1 km? If speed increases by a factor of 2, what happens to time? Speed is analogous to reaction rate and time of travel is analogous to reaction time.

Hint: number 3 will be simple after you get number 1
