Chapter 6, Problem 6G.3ST

Interpretation Introduction

Interpretation:

The diffusion-controlled rate constant for a reaction in benzene at ${25}^{°}C$ has to be estimated.

Concept Introduction:

Simple diffusion: The moment of molecules move down the concentration gradient is known as simple diffusion.

Facilitated diffusion: The moment of molecules against the (move up) the concentration gradient and changes the shape of the membrane is known as facilitated diffusion.

The rate of reaction is the quantity of formation of product or the quantity of reactant used per unit time. The rate of reaction doesn’t depend on the sum of amount of reaction mixture used.

The raise in molar concentration of product of a reaction per unit time or decrease in molarity of reactant per unit time is called rate of reaction and is expressed in units of $\text{mol/(L}\text{.s)}$ .

The equation that relates the reaction rate to the reactants concentrations that is raised to various powers is called as rate law.

Rate law can be determined by the slow step or otherwise called as rate-determining step.

Rate constant is defined as proportionality constant in the connection between rate and concentrations.
