Integrated Rate Laws Quiz

What is the primary reason most students are not required to derive integrated rate laws?

• They are not used in chemistry.

• They are not important.

• They are too simple.

• They involve calculus.

For a zero-order reaction, what is the rate law expression?

• Rate = [A]/k

• Rate = k

• Rate = k[A]^2

• Rate = k[A]

How does the rate expression differ from the rate law?

• Rate expression measures the rate, while rate law predicts it.

• Rate expression predicts the rate, while rate law measures it.

• Both measure the rate.

• Both predict the rate.

What is a common method to solve differential equations in the context of integrated rate laws?

• Laplace transforms

• Partial fraction decomposition

• Separation of variables

• Integration by parts

In the derivation of the zero-order integrated rate law, what is the integral of dA?

What is the integrated rate law for a zero-order reaction?

• [A] = [A]₀ + kt

• 1/[A] = 1/[A]₀ + kt

• ln[A] = ln[A]₀ - kt

• [A] = [A]₀ - kt
