Question:

(A) Which of the four cases in Table 13.3 would apply to each of the following reactions?

(a) N(g) + 3 H(g) 2 NH3(g), (b) 2 C(graphite) + 2 H(g)  CH4(g), A,H -92.22 kJ mol A,H = 52.26 kJ mol-1 =

(B) Under what temperature conditions would the following reactions occur spontaneously?

(a) The decomposition of calcium carbonate into calcium oxide and carbon dioxide. The reaction is endothermic. 

(b) The “roasting” of zinc sulfide in oxygen to form zinc oxide and sulfur dioxide. This exothermic reaction releases 439.1 kJ for every mole of zinc sulfide that reacts.
