Overview

Variation of Reaction Rate with Temperature

The learning objectives of this experiment are as follows:

• Understand the relationship between the reaction rate, k, the activation energy, E_a, and the temperature at which a reaction occurs.
• Become familiar with the Arrhenius equation for activation energy and be able to mathematically manipulate the equation to meaningfully graph experimental data.
• Use experimental methods to determine the activation energy of a reaction.

Intro

In the previous lab we studied a reaction using absorbance to determine the rate law and rate constant. In this lab we continue our study of kinetics by looking at the effect of temperature on the reaction rate. It is generally known that an increase in temperature increases the rate of a process of reaction. Your beach towel dries faster in the sun and milk keeps longer in the refrigerator. At higher temperatures molecules move more quickly, and will collide more frequently and with higher energy thereby increasing the rate of reaction.
