Chapter 21, Problem 20E

Interpretation Introduction

(a)

Interpretation:

The reason for expecting the following reaction to takes place to a significant extent as written should be determined.

${\text{BaCO}}_{\text{3}}\left(\text{s}\right){\text{ + 2CH}}_{\text{3}}\text{COOH }\left(\text{aq}\right)\to {\text{Ba}}^{\text{2+}}\left(\text{aq}\right){\text{ + 2CH}}_{\text{3}}{\text{COO}}^{\text{-}}\left(\text{aq}\right){\text{ + H}}_{\text{2}}\text{O}\left(\text{l}\right){\text{+CO}}_{\text{2}}\left(\text{g}\right)$

Concept introduction:

Chemical kinetics is a branch of physical chemistry which studies reaction rates. The rate of reaction or

reaction rate is the speed at which reactants are transformed into products. For any reaction amid reactants

A and B to yield product C $aA+bB\to cC$ the reaction rate is often found to have the form:

Here k is the reaction rate constant which is dependent on temperature.

Interpretation Introduction

(b)

Interpretation:

The reason for expecting the following reaction to takes place to a significant extent as written should be determined.

$\text{Ca}{\left(\text{OH}\right)}_{\text{2}}\left(\text{s}\right){\text{ + 2NH}}_{\text{4}}{}^{\text{+}}\left(\text{aq}\right)\to {\text{Ca}}^{\text{2+}}\left(\text{aq}\right){\text{ + 2NH}}_{\text{3}}\left(\text{aq}\right){\text{ +2H}}_{\text{2}}\text{O}\left(\text{l}\right)$

Concept introduction:

In chemical kinetics a reaction rate constant or reaction rate coefficient, k, quantifies the rate of a chemical reaction. For a reaction between reactants A and B to form product C a A + b B → c C the reaction rate is often found to have the form: Here k is the reaction rate constant that depends on temperature.

Interpretation Introduction

(c)

Interpretation:

The reason for expecting the following reaction to takes place to a significant extent as written should be determined.

${\text{BaF}}_{\text{2}}\left(\text{s}\right){\text{ + 2H}}_{\text{3}}{\text{O}}^{\text{+}}\left(\text{aq}\right)\to {\text{Ba}}^{\text{2+}}\left(\text{aq}\right)\text{ +2HF }\left(\text{aq}\right){\text{ + 2H}}_{\text{2}}\text{O}\left(\text{l}\right)$
