Physical chemistry experiment--Determination of activation energy and A reaction rate constant

Physical chemistry experiment
Determination of activation energy and A reaction rate constant

Experiment Purpose

• ·         Determine the value of activation energy for Na₂S₂O₃ (aq) with HCl (aq) reactions

• ·         Determine the value of reactions rate constant (k) in various temperature

 Introduction

Commonly, rate for the reactions affected by increase of temperature. For the common reactions, the rate increase two until three times for the temperature increase at 10 degrees. This related with the average increase of kinetic energy of the reactan because the increase of temperature that decrease barrier energy of the reaction and the reaction more easier to react.
