34. Given the decomposition of gaseous SO a) Use Hesss law to calculate the AHaa (in kJ) for the following reaction given the data below. Also, is this reaction endothermic or exothermic? ( pts.) (Circle one) Endothermic Exothermic SO2(g) → S(s) + 01g) -296.8 k, b) 1f1 2 1.0 Lofso,were decomposed at 914mmHg and 51.4℃, then calculate the heat (in kJ) associated with this reaction. (7 pts)

Given the decomposition of gaseous SO_3, 4 SO_3(g) Rightarrow 4 S(s) + 6 O_2(g) a) Use Hess’s law to calculate the Delta H_ (in kJ) for the following reaction given the data below. Also, is this reaction endothermic or exothermic? (Circle one) Endothermic Exothermic SO_2(g) Rightarrow S(s) + O_2(g) Delta H_ = 296.8 kJ 2 SO_2(g) + O_2(g) Rightarrow 2 SO_3(g) Delta H_ = -197.8 kJ If 121.0 L of SO_3 were decomposed at 914 mmHg and 51.4 Degree C, then calculate the heat (in kJ) associated with this reaction.
