Find K, at 600 K for N₂O4(g) = 2NO₂(g) (a) using the approximation that AH is independent of T; (b) using the approximation that AC, is independent of T; (c) using the NIST-JANAF tables (Sec. 5.9). (b) If AC is assumed independent of T, then Eq. (5.19) gives AH°(T) = AH (T) + AC (T) (T - T₁). Substitution of this equation into (6.37) gives an equation for In [K(T₂)/K(T)] that involves AC (T) as well as AH°(T₁); see Prob. 6.17. Appendix data give ACP.298 = -2.88 J/mol-K, and substitution in the equation of Prob. 6.17 gives (Prob. 6.17) KP.600 1.52 x 104. = Find K, at 600 K for N₂O4(g) = 2NO₂(g) (a) using the approximation that AH is independent of T; (b) using the approximation that AC, is independent of T; (c) using the NIST-JANAF tables (Sec. 5.9).
