Predict the sign of Delta S in the system for each of the following reactions.

Question

2H3O^+(aq) + CO3^2-(aq) ---> CO2(g) + 3H2O(l)

-,+, or 0?

Answer 1

Delta Srxn = sum So products - sum So reactants.
But the tables in my text (a freshman text) don't have S listed. If your does, it just a simple matter of substituting the numbers and running the above.
