The Arrhenius Equation and Activation Energy By Jennifer Partenio-Thrasher Course: CM104 Date & Time: Tues. February 4, 2003, 11:20 am- 2:40 pm Lab Partners: Bobbi Weber Tim Hall The Arrhenius Equation and Activation Energy Introduction: In this lab, our task is to determine how different degrees of temperature affect reaction rates. A Swedish chemist, named Svante Arrhenius discovered the relationship between temperature and reaction rate. In finding this relationship a new equation was formed called the Arrhenius Equation: Reaction rate constant k = A e -Ea/RT The factor A represents the frequency of collisions between two molecules in the proper orientation for reactions to occur. The value of A is determined by experiment and will be different for every reaction. The value of the exponential term e -Ea/RT describes the fraction of molecules with the minimum energy required to react, R is the gas constant, 8.314 J/mol-K, T is the temperature in Kelvin and Ea is the...
