Webchemical equilibrium, condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants. At equilibrium, the two opposing reactions go on at equal rates ... WebThe rate of this reaction depends on the amount of sulfur dioxide in the air ( Figure 12.7 ). An acidic oxide, sulfur dioxide combines with water vapor in the air to produce sulfurous acid in the following reaction: SO 2 ( g) + H 2 O ( g) H 2 SO 3 ( a q) Calcium carbonate reacts with sulfurous acid as follows: CaCO 3 ( s) + H 2 SO 3 ( a q) CaSO ...
