Question

Chapter 6, Problem 6G.2ST

Interpretation Introduction

Interpretation:

Whether the activation energy depends on the temperature or not has to be found and for the given viscosities the activation energy has to be evaluated.

Concept Introduction:

Activation energy(Ea): The potential energy barrier that must be surmounted before reactants can be converted to products.

Arrhenius equation:

Arrhenius equation is a formula that represents the temperature dependence of reaction rates

The Arrhenius equation has to be represented as follows f = e−Ea/RT

Ea represents the activation energy and it’s unit is kJ/mol

R represents the universal gas constant and it has the value of 8.314 J/K.mol

T represents the absolute temperature

f represents the frequency factor or collision frequency

Viscosity: It is η defined by ratio of force per wall area to the velocity gradient.

Example: F = Aη νh
