How do we calculate #DeltaG^@# for the reaction...? #Ca(OH)_2(s) + 2HCl(aq) rarr CaCl_2(aq) + 2H_2O(l)#

We need some data to answer your question.

Explanation:

We interrogate the reaction,

#Ca(OH)_2(s) + 2HCl(aq) rarr CaCl_2(aq) + 2H_2O(l)#

Now even without looking for the data, it is a fact that #DeltaG^@# for the given reaction is NEGATIVE at most lab temperatures, and thus in accord with the experimental result.

To quantify this problem we need #DeltaG_f^@# for the reactants and the products.
