What is the integrated rate law for a zero-order reaction?
[A] = [A]0 - kt
[A] = [A]0 + kt
[A] = [A]0e^(-kt)
[A] = kt + [A]0
Questions & Step-by-Step Solutions
What is the integrated rate law for a zero-order reaction?
Step 1: Understand what a zero-order reaction is. In a zero-order reaction, the rate of the reaction does not depend on the concentration of the reactant.
Step 2: Identify the variables in the integrated rate law. [A] is the concentration of the reactant at time t, [A]0 is the initial concentration, k is the rate constant, and t is time.
Step 3: Write down the formula for the integrated rate law of a zero-order reaction. It is [A] = [A]0 - kt.
Step 4: Interpret the formula. This means that as time (t) increases, the concentration of the reactant ([A]) decreases linearly.
Step 5: Remember that in a zero-order reaction, the concentration decreases at a constant rate, which is represented by the term 'kt' in the equation.
