4. Alkaline saponification of ethyl ester of acetic acid is characterized by the following values of the reaction rate constant at different temperatures:
Temperature, K 273 293 298
Rate constant, min-1l/mol 1.17 5.08 6.56
Determine the activation energy graphically, calculate the temperature coefficient of the reaction rate in the temperature range from 275 to 295 K.
