How is the reaction sugar + KNO3 =>?

C6H12O6 + 2KNO3 = K2O + N2 + 6CO + 6H2O
or
C6H12O6 + 4KNO3 = 2K2CO3 + 2N2 + 4CO2 + 6H2O

Mechanism? Nitrate breaks into oxygen and burns up the carbons...

5C12H22O11 + 48KNO3 = 60CO2 + 55H2O + 24K2O + 24N2

or

For the KN-sucrose propellant, with an oxidizer-fuel (O/F) ratio of 65/35, the theoretical combustion equation is as follows:

C12H22O11 + 6.288 KNO3 -> 3.796 CO2 + 5.205 CO + 7.794 H2O + 3.065 H2 + 3.143 N2 + 2.998 K2CO3 + 0.274 KOH
