Chapter 17, Problem 17.3P

(a)

Interpretation Introduction

Interpretation:

Experimental method to measure rate of the reaction given below has to be described.

    $\begin{array}{l}{\text{I}}_{\text{2}}(aq)+{\text{2S}}_{\text{2}}{\text{O}}_{\text{3}}{}^{2-}(aq)\to {\text{S}}_{\text{4}}{\text{O}}_{\text{6}}{}^{2-}(aq)+{\text{2I}}^{-}(aq)\\ yellowcolorlesscolorlesscolorless\end{array}$

Concept Introduction:

Rate of a reaction depends on the species concentration that takes place in the reaction.  Chemical kinetic experiments are used in order to deduce the rate of reaction.  Rate law of a reaction can only be identified by experimental methods that are adopted.

(b)

Interpretation Introduction

Interpretation:

Experimental method to measure rate of the reaction given below has to be described.

    ${\text{4PH}}_{\text{3}}(g)\to {\text{P}}_{\text{4}}(g)+{\text{6H}}_{\text{2}}(g)$
