Chapter 5, Problem 5.93

(choose chapter or problem)

Limestone stalactites and stalagmites are formed in caves by the following reaction: Ca2+ (aq) + 2 HC03 -(aq) -> CaC03(s) + COz(g) + HzO(/) If 1 mol of CaC03 forms at 298 K under 1 atm pressure, the reaction performs 2.47 kJ of P-V work, pushing back the atmosphere as the gaseous C02 forms. At the same time, 38.95 kj of heat is absorbed from the environment. What are the values of flH and of fl for this reaction?
