LETTERS TO THE EDITOR 550. (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 24. Web Lecture 24. Class Lecture 20-Thursday 3/28/2013. Chapter 14. 14.1. Factors that Affect Reaction Rates. Chemical kinetics. is the study of how fast chemical reactions occur.. Generally, the more frequently collisions between reaction particles occur, the faster the reaction.. Chapter 15. E-mail: . benzene4president@gmail.com.

What makes “superglue” bond instantly while Elmer’s glue does not?. What factors determine how quickly food spoils?. Why do “glow sticks” last longer when stored in the freezer?. Objective: I will . identify the same value relating the measures of x and the measures of y in a proportional relationship as the constant of proportionality and recognize it as the unit rate in the context of a given situation. . Representing Signals: Images and Sounds. Class 4. . 9 . Sep . 2014. Instructor: . Bhiksha. Raj. 9 Sep 2014. 11-755/18-797. 1. Representing Data. The first and most important step in processing signals is representing them appropriately. (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 24. Web Lecture 24. Class . Lecture . 20-Thursday. Review of Multiple Steady States (MSS). Lecture 14 . Reaction Rates. Recall that we defined the rate of reaction as the rate of production of the products, or equivalently, the rate of consumption of the reactants.. Reaction rates for elementary reactions depend on:.

Objective:. To establish the relationship between enzyme concentration and the rate of an enzyme catalyzed reaction.. The reaction rate will increase as the concentration of enzymes is increased but there must be a . 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). Chemical System: . A system is described in terms of empirical properties such as . temperature, pressure, volume and amount of substance present.. By definition, all chemical systems are fast, quantitative, stoichiometric and spontaneous! However, this assumption is NOT always true.. Step 1:. Energy must be . SUPPLIED. to break . bonds.. Step 2:. Energy is . RELEASED. when new bonds are . made.. A . reaction is . EXOTHERMIC. if more energy is RELEASED then . SUPPLIED (. hotter.
