Consider the reaction 2so2(g) + o2(g) mc021-1.jpg 2so3(g). substance mc021-2.jpghf (kj/mol) s (j/(molmc021-3.jpgk)) so3(g) –396 130.58 so2(g) –297 191.50 o2(g) 0 205.00 what is the mc021-4.jpggrxn of this reaction, and would it be spontaneous or nonspontaneous at 300.0 k? use mc021-5.jpgg = mc021-6.jpgh – tmc021-7.jpgs. –296 kj/mol, spontaneous –296 kj/mol, nonspontaneous –100 kj/mol, spontaneous –100 kj/mol, nonspontaneous

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
