The formation of nitrogen trichloride is N₂(g) + 3Cl₂(g) ⇄ 2NCl₃(g) +N₂ ( g ) + 3Cl₂ ( g ) ⇄ 2 NCl₃( g )
This reaction is endothermic: ΔH = +232 kJ∙mol–1 Which change will increase the concentration of the product?
1) removing nitrogen
2) decreasing the volume of the container
3) adding Ne (g)
4) decreasing the temperature
