what is the solubility product of borax at each of the
measured temperatures?
1) T = (273 + 4.5) = 277.5 K
ln Ksp = - 9525.5 / T + 27.628
or
ln Ksp = - 9525.5 / 277.5 + 27.628
or
Ksp = 1.23 * 10^-3
2) T = (273 + 21.5) = 294.5 K
ln Ksp = - 9525.5 / T + 27.628
or
ln Ksp = - 9525.5 / 294.5 + 27.628
or
Ksp = 8.95 * 10^-3
3) T = (273 + 37.0) = 310 K
thus
Ksp = 4.51 * 10^-2
4) T = (273 + 43.0) = 316 K
Ksp = 8.07 * 10^-2
5) T = (273 + 53.5) = 326.5 K
Ksp = 0.213
What is the solubility product of borax at each of the measured temperatures?
A series of experiments were conducted where the equilibrium constant (K) was determined at various temperatures (T). The data was then graphed (shown below). The equation of the line is listed on the graph. Use the graph to determine AH° (in kJ/mol). -30 0.0031 0.0032 0.0033 0.0034 0.0035 0.0036 0.0037 -30.50.003 -31 y = -6861.2x - 9.2495 -31.5 -32 -32.5 In -33 -33.5 -34 -34.5 -35 1/T in K
