Answer is:
Redox reaction: MnO₂ + 4H⁺ + 2Cl⁻ → Mn²⁺ + 2H₂O + Cl₂.
Cl⁻ lost one electron (two Cl⁻ lost two electrons) and change oxidation number to zero, so Cl⁻ is reducing reagent. 
Mn change oxidation number from + 4 to +2, Mn is oxidizing reagent.
Hydrogen don't change oxidation number.

Thermodynamics:

Combustion of the compound is reaction with oxygen.

The carbohydrates contain more content of oxygen as compared to fats.

Hence, carbohydrates have lot of oxygen content which are already partially oxidized as compared to fats. Hence, combustion of the carbohydrates is a faster process.

Kinetics:

The molecular reacts also shows that the combustion of the carbohydrates is a faster process.
