Ответ:
You have to find the value of enthalpy of formation since the reaction is the standard heat of information. The value is -1223.8. This represents the amount of heat released when 1 mol of UO3 is formed. Now 1 mol of UO3 needs 3/2 moles of O2(g).
The equation will look like this
-1223.8kJoules / molUO3 x 2molO2 = -815.7 kJ
3mol uO3 molO2 (g)
