Chapter 18 - Kinetics 2

Question 1

What non-environmental factors affect the rate of the reaction?

Answer 1

The order of the reactants and their concentrations. This is given in the rate equation:
Rate = k[A]^m[B]^n, where m and n are orders and k is a constant (m and n cannot be more than 0,1 or 2)

Question 2

What does k vary with, and which equation shows this?

Answer 2

K changes with temperature, and this is shown in the arrhenius equation, which is given in an exam

Question 3

What does rearranging the arrhenius equation allow you to do?

Answer 3

It allows you to plot a straight line graph of the rate of a reaction

Question 4

How is the rate equation of an experiment determined?

Answer 4

Through experimental data

Question 5

What do the orders of different reactants allow you to determine?

Answer 5

The mechanism of the reaction in regards to rate limiting factors - particularly the rate determining step of a reaction

Question 6

What is the rate determining step and how can it be overcome?

Answer 6

The rate determining step is the slowest part of a reaction and takes up a large part of the rate of reaction, and by increasing the concentration of the reactant involved in this step you can reduce the effect that it has on the rate of the reaction
