Chemistry
In anaerobic cells glucose C6H12O6 is converted to lactic acid:C6H12O6 → 2CH3CH(OH)COOH. The standard enthalpies of formation ofglucose and lactic acid are –1274.45 and –694.04 kJ/mol,respectively. The molar heat capacities (at constant pressure) forglucose and lactic acid are 218.86 and 127.6 J/mol K,respectively.
(4.a) Calculate the molarenthalpy associated with associated with the formationlactic acid from glucose at 298 K.
(4.b) What would the quantity in part (4.a) beif the reaction proceeded at a physiological temperature of 310K?
(4.c) Based on your answers in parts (4.a) and(4.b) how sensitive is the enthalpy of this reaction to moderatetemperature changes?
