Chapter 14, Problem 14.139AP

(a)

Interpretation Introduction

To determine: The dependence of the reaction rate on the concentration of ${\text{HNO}}_{\text{2}}$ by the given data.

Interpretation: The dependence of the reaction rate on the concentration of ${\text{HNO}}_{\text{2}}$ is to be stated.

Concept introduction: In first order reaction rate is dependent on the concentration of reactant. The curve versus $\ln \left[{\text{HN}}^{\text{18}}{\text{O}}_{\text{2}}\right]$ and time is linear. In the second order reaction rate of reaction varies with concentration and curve versus $\ln \left[{\text{HN}}^{\text{18}}{\text{O}}_{\text{2}}\right]$ and time is not linear.

(b)

Interpretation Introduction

To determine: If the reaction rate depend on the concentration of ${\text{H}}_2{}^{18}\text{O}$.

Interpretation: The validation of the given statement that the reaction rate depend on the concentration of ${\text{H}}_2{}^{18}\text{O}$ is to be stated.

Concept introduction: In first order reaction rate is dependent on the concentration of reactant. The curve versus $\ln \left[{\text{HN}}^{\text{18}}{\text{O}}_{\text{2}}\right]$ and time is linear. In the second order reaction rate of reaction varies with concentration and curve versus $\ln \left[{\text{HN}}^{\text{18}}{\text{O}}_{\text{2}}\right]$ and time is not linear.
