Consider a reaction A → B. At 33.5 °C, the rate constant, k, for this reaction is 0.00918 s1. After the addition of an enzyme (a biological catalyst), the rate constant increases to 6.98 s¹. Calculate the absolute change in activation energy (AE) in kJ/mol for the reaction due to the presence of the enzyme. Assume the pre-exponential factor (A) is constant. R=0.08206 L-atm mol-K = 8.314 mol-K TkTc+273.15 Report your answer as a positive number with three significant figures and without the unit. Example: 90.0. Be sure your answer is in units of kJ/mol not J/mol.

Consider a reaction A → B.
At 33.5 °C, the rate constant, k, for this reaction is 0.00918 s ¹. After the addition of an enzyme (a biological catalyst), the rate constant increases to 6.98 s1. Calculate the
absolute change in activation energy (AE) in kJ/mol for the reaction due to the presence of the enzyme. Assume the pre-exponential factor (A) is constant.
