1. Firstly, how do you calculate the molar solubility of AgBr when given 0.1 M AgBr at 25 degrees C (Ksp = 5 x 10^-3)?
If show me a few examples of how to calculate molar solubility when you're given different things, I would appreciate it.
2. Next, how can I calculate the squilibrium direction of CO2 at 25 degrees C and 927 degrees C for the following reaction:
CaCO3 --> CaO (s) + CO2 (g) ?
1) Ksp = [Ag][Br]
AgBr = Ag + Br
Let the initial concentration of AgBr be given be C(AgBr) Initial concetration of Br be C(Br) and initial concentration of Ag be C(Ag) the reaction is balanced in charge and mass, please bear with no charges in this discussion. Also concentrations are really activities regarding a chemical potential for the transition but have been simplified to concentrations. For low concentration in the products the activity is taken as the concentration. Finally in the equation for Ksp the activity of the solid is taken as unity.
In the reaction ...
The solution works through the problems of solubility and Gibbs free energy in a brief discussion of the theory with some basic equations to look at as well.
