![If the half life of a certain second-order reaction (see below) is 56 s when the concentration of AB is 2.0 M, how
long (in seconds) does it take for the [AB] to drop to 0.25 M?
2 AB → A2 + B2
Your answer should have 3 significant figures.
Answer:
At 500°C, cyclopropane (C3H6) rearranges to propene (CH3-CH=CH2). The reaction is first order, and the rate
constant is 6.7 x 10-4 s1. If the initial concentration of C3H6 is 0.076 M, how many minutes does it take for the
C3H6 concentration to drop to 0.023 M? Your answer should have two significant figures.
