Chapter 12: Q1. (page 373)

Write the rate equations for a first-order and a second-order reaction.

Short Answer

Expert verified

The rate equation for a first-order reaction is $k = \frac{1}{t} ln \frac{{[A]}_{0}}{[A]}$ and the rate equation for a second-order reaction is $k = \frac{1}{t} (\frac{1}{[A]} - \frac{1}{{[A]}_{0}})$ .

Step by step solution

Rate equation

A chemical reaction's rate law (also known as the rate equation) is an expression that establishes a link between the reaction's pace and the concentrations of the reactants involved.

The pace at which reactants are consumed or products are created is known as the rate of a chemical reaction.

First-order reaction

The rate equation for first-order reaction is,

$k = \frac{1}{t} ln \frac{{[A]}_{0}}{[A]}$

where,

k= Rate constant

Second-order reaction

The rate equation for second-order reaction is,

$k = \frac{1}{t} (\frac{1}{[A]} - \frac{1}{{[A]}_{0}})$

where,

k=Rate constant

As a result, we may assume that raising a substance's concentration will increase the reaction rate.
