Step 1

Given reactions are : help_outlineImage Transcriptionclose2 H2 (g)O2 (g)»2 H20 (l AH -571.6 kJ ......(1) S (s) H2 (g)2 O2 (g)H2SO4 (l) AH814.0kJ ......(2) 2 SO3 (g) AH 196.6 kJ ......(3) O2 (g)2 SO2 (g) SO2 (g)O2 (g)S (s) AH 296.84 kJ .....(4) fullscreen
Step 2

Reversing equation (1) and dividing by 2, the enthalpy value will change in sign and get divided by 2, we get,

Step 3

Dividing equation (3) by 2, so the enthalpy...
