Given the following solubility vs. temperature data for two compounds, answer the questions below
Compound A
temperature degrees C 25.0 26.7 30.8 41.7 48.0 63.0
solubility, mol L-1 5.60 5.81 6.23 6.46 6.71 7.27
Compound B
temperature degrees C 25.0i 38.6 43.4 49.0 52.0 56.2 60.0 67.2
solubility, mol L-1 3.54 6.28 7.17 8.37 9.13 10,0 11.2 12.6
1) Which compound's solubility is more affected by changes in temp? Explain.
2) For each compound, determine the percent error in calculated solubility if the determination was supposed to have been made at 25 degrees C, but the stirring motor actually heated the solution to 35 degrees C.
