2+ 3. For CaF2(s) Ca- (aq) + 2F-(aq), K = 3.9x10-11 at 25°C and the standard Gibbs energy of formation of CaF2(s) is ) -1167 kJ/mol. Calculate the standard Gibbs energy of formation of CaF2(aq). .
6. For dilute solutions the osmotic pressure (II) is given by the van't Hoff equation: II = RT, where = nB/V is the molar concentration of the solute. Derive the van't Hoff equation. = =
