Question

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

Answer 1

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.
