Question:

Under anaerobic conditions, glucose is broken down in muscle tissue to form lactic acid according to the reaction: C6H12O6(s) †’ 2CH3CHOHCOOH(s). Thermodynamic data at T = 298 K for glucose and lactic acid are given below.

Cp(J K-- mol-) s°(JK- mol-) AH,kJ mol) -1273.1 219.2 209.2 Glucose(s) Lactic Acid(s) -673.6 127.6 192.1

Calculate ΔS for the system, the surroundings, and the universe at T = 325.K. Assume the heat capacities are constant between T = 298 K and T = 330.K.
