General Integrated Rate Problems
- What
is the rate constant of a zero order reaction if it takes 87 seconds for a
concentration of 0.32500M to decompose to 0.00387M?
- A
compound of 0.0452M has a rate constant of 4.95 x 10-5 M/s and
decays to 0.0042M. How long did
this process take?
- After
335 seconds, only 0.029M of the mixture is left. Find the concentration of the initial mixture at a rate of
0.68M-1s-1.
- For a
first order reaction, in 4 minutes a solution went from 0.0800M to
0.0060M. What is the rate constant
for the reaction?
- Beginning
with 0.5046M of a substance that has a rate constant of 0.085s-1. How much for the substance is left
after 25 seconds?
- With a
rate constant of .019M-1s-1, how long does it take a
chemical to go from 0.0400M to 0.0020M?
