C6H12O6 ------------------ 2 C2H5OH + 2 CO2
Concentration of C6H12O6 = 0.08M
Concentration of C2H5OH = 0.10M
Concentration of CO2 = 1.5
Kc = [C2H5OH]^2 [ CO2]^2/ [C6H12O6]
Kc = ( 0.10)^2 (1.5)^2 / ( 0.08)
Kc = 0.28125
Equilibrium constant = Kc = 0.281

The human body converts glucose (C6H12O6) to carbon dioxide and water. The balanced chemical equation for the reaction is: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O If you ate a candy bar that contained 22.2 g of glucose (C6H12O6), how many grams of water will the body produce from the glucose you ate? How many grams of CO2 would that make?
