Use the diagram (potential energy vs reaction coordinate, catalyzed and uncatalyzed curves) below to answer questions 26. In the diagram, the respective activation energies for the catalyzed and uncatalyzed reactions in kJ are
- A. 50 and 45Correct
- B. 48 and 45
- C. 8.45 and 50
- D. 30 and 35
Explanation
Reading the peaks of the two curves on the diagram, the uncatalyzed reaction has a higher activation energy (50kJ) than the catalyzed reaction (45kJ).
