What is the change in enthalpy when 4.00 mol of sulfur trioxide decomposes to sulfur dioxide and oxygen gas? 250 2(g) + O2(g) ®
lidiya [134]

Answer: A. -396 kJ

Explanation:

The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.

2SO_2(g)+O_2 (g)\rightarrow 2SO_3(g)  \Delta H^0=198kJ

Reversing the reaction, changes the sign of \Delta H

2SO_3(g)\rightarrow 2SO_2(g)+O_2 (g)  \Delta H^0=-198kJ

On multiplying the reaction by 2, enthalpy gets multiplied by 2:

4SO_3(g)\rightarrow 4SO_2(g)+2O_2 (g)   \Delta H=2\times -198kJ=-396kJ

Thus the enthalpy change for the reaction 4SO_3(g)\rightarrow 4SO_2(g)+2O_2 (g)  is -396 kJ.
