The triple bond in the N2 molecule is very strong, but at high enough temperatures even it breaks down. At 5000 K, when the total pressure exerted by a sample of nitrogen is 1.00 atm, N2(g) is 0.65% dissociated at equilibrium: N2(g) 2 2 N(g) At 6000 K with the same total pressure, the proportion of N,(g) dissociated at equilibrium rises to 11.6%. Use the van't Hoff equation to estimate the AH of this reaction.
