H2O2 → H2O+ ½ O2
Hydrogen peroxide decomposes to produce water and oxygen according to the equation above. An experimentally determined graph for the first-order decomposition of hydrogen peroxide is provided below.
Which of the following best identifies the rate constant k for the reaction based on the information in the plot of ln[H2O2] versus time (t)?
O k = ln[H2O2] at t = 0s
O k = ln[H2O2] at t = 500s
O k = −(slope of plot)
O k = −1/(slope of plot)
