Chemistry Chapter 6: Kinetics

Question 1

When is a species most likely to exist as a radical?

Answer 1

When it has an odd number of valence electrons

Question 2

What is k equal to for a zero order reaction?

Answer 2

the rate law is just the rate constant (rate = k) and a plot of the reactant concentration over time will be a straight line with -k = slope of the line.

Question 3

When do zero order, first order and second order reactions result in a straight line?

Answer 3

For a second-order reaction → 1/[A] vs. time gives a straight line.
For a first-order reaction → ln[A] vs. time gives a straight line.
For a zero-order reaction → [A] vs. time gives a straight line.
