PPT-Chemical Reaction Engineering

CRE is the field that studies the rates and mechanisms of chemical reactions and the design of the reactors in which they take place Lecture 9 1 Lecture 9 Thursday 272013 2 Balances in terms of molar flow rates. Chemical change. . Reactions with acid. . Reactions with oxygen . 7F. 7F Simple chemical reactions. Chemical change. . 7F Simple chemical reactions. 7F Chemical change – Changing materials. How many different materials can you see in this bedroom?. Chemical Reactions. Investigation One. Chemical compounds are formed when two or more elements combine.. H. ₂ + O .  H₂O (water). Na + . Cl.  . NaCl. ( Sodium Chloride – Salt). Chemical Compounds. (CRE) is the field that studies the rates and mechanisms of chemical reactions and the design of the reactors in which they take place.. Lecture 1. 1. Lecture 1 – Thursday 1/10/2013. 2. Introduction. 10/20/14. What are Physical Properties?. Physical properties can be . observed. and measured without changing the . identity. of the substance. . Phase. Changes: . Melting. Point: the temperature at which a substance . Because . entropy is a state function, . the property is what it is regardless of pathway, the . entropy change for a given reaction can be calculated by taking the difference between the . standard entropy.

Hunter, “Chemistry Laboratory Manual (CHEM 162)”, Michigan State University. Color change. Increase or decrease in temperature. Gas production (not boiling). Precipitation: 2 liquids react to make a solid. Change in properties (density, smell, taste, texture, melting points, boiling points, hardness, etc.). Stoichiometry. (identity and relative amounts of reactants and products).. Spontaneity (feasibility of the reaction, based on thermodynamics).. Speed…KINETICS (reaction rates).. Stopping…when will the reaction stop? (Equilibrium-next chapter). All. chemical reactions either release or absorb energy. . The energy can take many forms: . HEAT. , . LIGHT. , . SOUND. , and . ELECTRICITY. . Chemical . bonds. are the source of this energy. . Nikhil . Gopalkrishnan. (From presentation of Chen, Doty, .
