Question

Describe the integrated rate law method for determining the order of a first order reaction.

Answer 1

The integrated rate equation for a first order reaction can be represented in the following forms.

[A] = [A]₀e^−kt

\[\ce{k = \frac{2.303}{t} log_10 \frac{[A]_0}{[A]}}\]

\[\ce{k = \frac{2.303}{t} log_10 \frac{a}{a - x}}\]

where a = initial concentration, x = amount reacted in time t.
