Question

Geoscientists usually bring a solution of HCl to test for the presence of CaCO3 in rocks. The reaction of HCl(aq) with CaCO3 (s) is expressed by the following reaction: HCl(aq) + CaCO3 (s) > CO2 (g) + H2O (l) + CaCl2. The table below shows the standard thermodynamic properties of the reactants and products of the above reaction.
a. Determine whether the above reaction is exothermic or endothermic.
b. Determine the delta f G° for this reaction. Explain why this parameter is considered important?
c. Using the table below, can you determine the work and internal energy changes for this reaction?
