The first-order decomposition of hydrogen peroxide occurs according to the equation 2 H₂O₂(aq) → 2 H₂O(l) + O₂(g)
Using data from a concentration-time study of this reaction,which plot will produce a straight line?

The integrated rate law for a pseudo-first order reaction is:

ln([A]t/[A]0) = -kt

Where [A]t is the concentration of hydrogen peroxide at time t, [A]0 is the initial concentration of hydrogen peroxide, k is the rate constant, and t is time.

Taking the natural logarithm of the concentration of hydrogen peroxide and plotting it versus time will produce a straight line. Therefore, the best choice is D.
