Sucrose, C12H22011, is table sugar, and it has a (enthalpy of reaction) AH. of –5639.7 kJ/mol. Determine the AH; of sucrose given AH+ (H2O(1)) = -285.8 kJ/mol, and AH+ (CO2(g)) = -393.5 kJ/mol. [3] C12H22O4(s) + 12 O2(g) → 12 CO2(g) + 11 H2O(1)
4. Sucrose or common sugar (C12H22011) is hydrolyzed with water to form fructose (CeH120) and glucose (CoH1206). The mix of fructose and glucose is known as inverted sugar and it is very important because it does not crystallize, so soft candies can be produced. From the following kinetic data, determine: 0 60 Reaction time (min) 96.4 157.5 [C12H22O11] (mol L.) a) The order of the reaction; b) Time required for 50% of sucrose to hydrolyze; e) For an ideal perfect...
