The value of ΔGo for the precipitation reaction,

Ca2+(aq) + CO32-(aq) <=> CaCO3(s)

is -48.1 kJ at 298 K.

Calculate the value of ΔG in kJ at 298 K if the concentrations of Ca2+(aq) and
CO32-(aq) are 2.97 and 1.09, M respectively---> please show steps and how you get any ratios (the ans should be -51.01)

CORRECT ANSWER: -43.9

Limestone stalactites and stalagmites are formed in caves by the following reaction: Ca2+(aq)+2HCO−3(aq)→CaCO3(s)+CO2(g)+H2O(l) If 1 mol of CaCO3 forms at 298 K under 1 atm pressure, the reaction performs 2.49 kJ of P−V work, pushing back the atmosphere as the gaseous CO2 forms. At the same time, 38.95 kJ of heat is absorbed from the environment.
