(a) For a second-order reaction, what quantity, when graphed versus time, will yield a straight line?
1) The natural log of the concentration.
2) The concentration.
3) The inverse of the concentration.
4) The inverse of the natural log of the concentration.
5) The square of the concentration.
(b) How do the half-lives of first-order and second-order reactions differ?
1) The half-life of a first-order reaction is independent of [A]0, whereas the half-life of a second-order reaction does depend on [A]0.
2) The half-life of a first-order reaction depends on [A]0, whereas the half-life of a second-order reaction depends on 1 / [A]0.
3) The half-life of a first-order reaction depends on 1 / [A]0, whereas the half-life of a second-order reaction depends on ln([A]0).
4) The half-life of a second-order reaction is independent of [A]0, whereas the half-life of a first-order reaction does depend on [A]0.
