muscles then relax allowing a decrease in the volume of the thorax. The decreased volume increases the pressure in the lungs‚ so the pulmonary pressure is now greater than the atmospheric pressure‚ thus is forced out of the lungs. Gas exchange takes place through a gas exchange surface‚ (also known as a respiratory surface) and is the process of getting oxygen by taking air into the blood‚ and the removal of carbon dioxide waste from the blood into the air. The removal of carbon dioxide from the

EXPERIMENT 5 GAS DIFFUSION COEFFICIENT OBJECTIVES: Determine the gas diffusion coefficient of acetone using the established Winkelmann’s method KEYWORDS Diffusivity‚ Gas Diffusion Coefficient‚ Winkelmann’s method OVERVIEW The knowledge of physical and chemical properties of certain materials is important because very often process engineering deal with the transformation and distribution of these materials in bulk. One such property is diffusivity. Mass transfer by diffusion takes

the oxygen gas created into a container thus showing the extent of the reaction and this will show the rate in which oxygen is created and how the rate will change when we use different initial concentrations. We do use a catalyst in this reaction to speed up the process and lower the activation energy needed to run the reaction. The catalyst is the Iodide ion that will be used in the form of potassium iodide (KI). Results at the end of the trails will be used to compose a rate of law for the reactions
