Sulfur dioxide SO2 is released in the combustion of coal. Scrubbers use aqueous slurries of Ca(OH)2 to remove the sulfur dioxide from the flue gases. Write a balanced equation for this reaction and calculate delta So at 298 K (So for CaSO3(s) = 101.4 J/{mol*K}).

include the states of all reactant and products in the equation..

thanks.

• Chemistry -

Ca(OH)2(aq) + SO2(g) ==> CaSO3(s) + H2O(l)

You will need So for each component, then
dSo rxn = (n*dSo products) - (n*dSo reactants)
