Reaction Rates and Temperature Leaming Goal: To use the Antenius equation to calculate the activation energy As temperature rises, the average kinetic energy of molecules increases. In a chemical reaction, this means that a higher percentage of the molecules possess the required activation energy, and the reaction goes faster. This relationship is shown by the Authenius equation k Aer where & is the rate constant. A is the frequency factor. E, is the activation energy R-83145 J/(K-mol) is the gas constant, and 7' is the Kelvin temperature. The following rearranged version of the equation is also useful In (:)-(*) (#-#) where it is the rate constant at temperature 7; and ky is the rate constant at temperature 7. The rate constant of a chemical reaction increased from 0.100 s¹ to 2.70s upon raising the temperature from 25.0°C to 49 0 °C Part A of (+-+) - Express your answer numerically.

Learning Goat: To use the Arrhenius equation to calculate the activation energy As temperature rises, the average kinetic energy of molecules increases. In a chemical reaction, this means that a higher purcentage of the molecules possess the required activation energy, and the reaction goes faster. This relationship is shown by the Arrhenius equation RE Ae where & is the rate constant. A is the frequency tactor. E is the activation anargy. It-63145 J/(K-mol) is the gas constant, and is the Kelvin temperature. The following rearranged version of the equation is also useful In(:)= (*) (*-*) where ky is the rate constant at temperature T and Ay is the rate constant at temperature 2 ▾ Part B Calculate the value of Ini In In() Express your answer numerically View Available Hint(s) Submit Part C where k, and ky correspond to the rate constants at the initial and the final temperatures as defeed in part A2:4 Red 1 Contacts I Paric What is the activation anergy of the reaction?
