What is the activation energy for acid hydrolysis of sucrose?
Question

What is the activation energy for acid hydrolysis of sucrose?

A.

6.21 kJ mol⁻¹

B.

6.20 kJ mol⁻¹

C.

6.22 kJ mol⁻¹

D.

6.24 kJ mol⁻¹

Correct option is C

The correct answer is (C) 6.22 kJ mol⁻¹

Explanation:
• The activation energy for the acid-catalyzed hydrolysis of sucrose (inversion of cane sugar) is widely referenced as 6.22 kJ mol⁻¹ in standard chemical kinetics literature.
• This reaction involves the cleavage of sucrose into glucose and fructose.

Information Booster:
• When an enzyme (like sucrase/invertase) catalyzes this reaction instead of acid, the activation energy decreases significantly, demonstrating the efficiency of biological catalysts.

Additional Knowledge:
• The values provided in options A, B, and D are extremely close distractors, but 6.22 kJ mol⁻¹ is the exact empirically measured standard value tested in chemistry.
