2S (s) + 3O2 (g) 2SO3 (g), H = 792 kJ

2S (s) + 2O2 (g) 2SO2 (g), H = ?

2SO2 (g) + O2 (g) 2SO3 (g), H = 198 kJ

What is the missing H?

**DrBob222**, Tuesday, April 10, 2012 at 3:50pmAdd equation 1 to the reverse of equation 3 and I believe that will give you equation 2. Then add 792 to -198 to find the missing H.
