Does hydrogen gas react with sulfur dichloride.

Answer 1

Hi Jack A.,

To solve this problem you need to do a little calculation. Write the balanced equation, the H goes to HCl and H2S. Then total up the bond enthalpies (look them up!) and figure the enthalpy change. There will be an entropy change, too, and you need to know the state-of-matter of the SCl2. Put that together, to get a free-energy change for the reaction. IF (-), then it will proceed spontaneously (which doesn't necessarily mean immediately!).

My gut feeling is that the reaction does go forward, since HCl is a strongly polar bond, H2S and SCl2 less polar, and there is at least 1 mole of additional gas produced.
