Chapter 16, Problem 16.41P

(a)

Interpretation Introduction

Interpretation:

Gaseous dinitrogen pentoxide first-order decomposition,

  ${\text{2N}}_{\text{2}}{\text{O}}_{\text{5}}\left(\text{g}\right)\to {\text{4NO}}_2\left(\text{g}\right){\text{ + O}}_2\left(\text{g}\right)$

At 60⁰C, the rate constant is $k\text{ = 2}\text{.8}\times {\text{10}}^{-3}{\text{s}}^{-1}$ . N₂O₅ has an initial concentration of 1.58 mol/L.

After 5.00 minutes, [N2O5] needs to be calculated.

Concept Introduction :

A chemical reaction that has a reaction rate that is linearly dependent on the concentration of just one ingredient is known as a first-order reaction. In other terms, a first-order reaction is a chemical reaction in which only one of the reactants' concentrations changes, and the rate of the reaction changes as a result.

(b)

Interpretation Introduction

Interpretation:

It is necessary to determine how long it will take for 35% of the N₂O₅ to decompose.
