Part A If a temperature increase from 10.0 °C to 22.0 °C doubles the rate constant for a reaction, what is the value of the activation barrier for the reaction? Express your answer in kilojoules per mole to three significant figures. • View Available Hint(s) ? E = kJ/mol Submit Previous Answers Request Answer X Incorrect; Try Again; 5 attempts remaining Use the two-point form of the Arrhenius equation to calculate the activation barrier: k2_ E R 1 T2 where ki and k2 are the rate constants of the chemical reaction at the initial (T¡ ) and final (T2) temperatures, respectively, E, is the activation energy of the reaction, and R is the gas constant. Rearrange this equation to solve for Ea. You may want to review Hint 1. Convert the temperatures from degrees Celsius to kelvins.
