The two isomers exist in equilibrium as represented by the equation below. n-butane(g) ̈ Æ isobutane(g) Kc = 2.5 at 25°C. Suppose that a 0.010 mol sample of pure n-butane is placed in an evacuated 1.0 L rigid container at 25°C. (c) Write the expression for the equilibrium constant, Kc, for the reaction. E° = ^(reduced species) - E°(oxidized species) = 1.36 V - 1.07 V = +0.29 V. Because E° for the reaction has a positive value, the reaction is thermodynamically favorable. point is earned for the correct balanced equation. point is earned for the correct calculation of E°. Br2 and Cl2 can react to form the compound BrCl.
