Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state theory‚ the activation

1. In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions. The transfer of energy can occur in a variety of ways‚ among them conduction‚radiation‚ and convection. The SI unit of heat is the joule. Heat can be measured by calorimeter‚ or determined indirectly by calculations based on other quantities‚ relying for instance on the first law of thermodynamics. In calorimeter‚ the concepts of latent heat and of sensible heat are used. Latent heat produces

We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. In this experiment we will be measuring the rate of decomposition of hydrogen dioxide with the following reaction: 2 H202 (aq) 4 2 H20 (l) + 02 (g) We can trap the
