What is AH in the equation AG = AH- TAS? O A. The change in specific heat between the products and the
reactants
B. The change in free energy between the products and the reactants
C. The change in entropy between products and reactants in a
reaction
OD. The change in enthalpy between products and reactants in a
reaction

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 .
