Question

why is the answer C? Please kindly explain step by step. Thank you.

Solubility (8 in 100mL of solution) 35.0 T31)The solubility of barium hydroxide in water was measured as a function of temperature. Use the graph produced in that experiment (shown here) to determine the 4Gº for the solubility of barium hydroxide at 25°C. MM(Ba(OH)2) = 171.34g/mol a. 22.9 kJ/mol b. 15.4 kJ/mol C. 5.72 kJ/mol d. -4.00 kJ/mol e. -6.09 kJ/mol 0 10 20 30 40 T(OC) 50 60 70 80 A6 = AH-TAS acº= 671.34) (290) 20-216)- 107
