Monarch caterpillars consume milkweed plants and Viceroy caterpillars eat willows. You can tell the difference between the two now by their flight patterns. I would say the answer to your question is that though they are similar, Viceroy were the “uglier” for the simple reason of survival. Predators would find their coloration as un-tasty.

The equilibrium constant k for the synthesis of ammonia is 6.8x105 at 298 k. what will k be for the reaction at 375 k?

spayn [35]

Answer is: K be for the reaction at 375 K is 326.
Chemical reaction: N₂(g) + 3H₂(g) ⇌ 2NH₃(g); ΔH = -92,22 kJ/mol.
T₁ = 298 K
T₂ = 375 K
ΔH = -92,22 kJ/mol = -92220 J/mol.
R = 8,314 J/K·mol.
K₁ = 6,8·10⁵.
K₂ = ?The van’t Hoff equation: ln(K₂/K₁) = -ΔH/R(1/T₂ - 1/T₁).
ln(K₂/6,8·10⁵) = 92220 J/mol / 8,314 J/K·mol (1/375K - 1/298K).
ln(K₂/6,8·10⁵) = 11092,13 · (0,00266 - 0,00335).
ln(K₂/6,8·10⁵) = -7,64.
K₂/680000= 0,00048
K₂ = 326,4.

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison
