Question

THERMODYNAMICS

Please answer the following below

3. After running for a long distance available oxygen in muscle is consumed. To produce energy under normal conditions (aerobic) glucose and O2 react according to the equation, CsH1206 (s)6 02 (g) 6CO2 (g)6 H20 (l) When deprived of O2, lactic acid is produced from glucose (glycolysis). The oxidation of lactic acid proceeds according to the equation, CH3CH(OH)COOH (s) 302 -> 3CO2 (g) 3H20 (l) Based on the two reactions above, calculate the standard enthalpy (ArHo) for the glycolysis of glucose to lactic acid, CsH1206 (s) > 2CH3CH(OH)COOH (s) Comment on the relative merits of aerobic versus anaerobic oxidation to produce energy in All these reactions take place at 1 bar. Assume data at 25°C is sufficiently close to that at 37°C that a correction for this this temperature difference with tabulated data is not necessary. Use thermodynamic data from Tinoco.
