Question

Antimony pentachloride, SbCl5, decomposes according to the following equation:

←

SbCl5(g) → SbCl3(g) +Cl(g)


An equilibrium mixture in a 5.00 L flask at 448 °C contains [SbCl5] = 0.002575 M, [SbCl3] = 0.008014 M and [Cl2] = 0.008011 M


1.State the type of equilibrium in the reaction


2.Calculate the mass in grams of each species that will be found when the mixture is transferred into a 2.00 L flask at the same temperature.

Answer 1

homogeneous mixture

1.048 g SbCl₅, 1.615 g SbCl₃, 0.496g Cl₂
