You perform an experiment using 2 different temperatures. When you increase the temperature from 23.0 oC to 37.0 oC, you determine that the rate constant increased by 4 times. Calculate the activation energy in kJ/mol for the reaction.Your answer must include the decimal point and the number after the decimal point.
