please solve the question
EFFECT OF TEMPERATURE ON SOLID - SOLUTION EQUILIBRIUM Benzoic acid is dissolved in water at three different temperatures and benzoic acid including samples are titrated with 0.1 N of NaOH solution. According to this step the following data will be obtained in this section of the experiment; the titration data will be given as below: Temperature, K Ti = 250 T2 = soc Volume of NaOH used in the titration, ml VI = 1,5mL VT = 2mL VT 3mL T3 = 68C Regarding these data follow the procedure explained below to perform the calculations; 1) Use the equation, N, V, = N2 V2 in order to calculate the concentration of benzoic acid dissolved at each temperature (N is the Normality and V is the volume). 2) Calculate Kc) (The concentration of benzoic acid is equal to the equilibrium constant, Kc). 3) Draw a plot of InKc vs. 1/T and find AS (entropy change) and AH (entalpy change). 4) Calculate Gibbs free energy change, AG. 5) Report the calculated data in the following tables; Table 3.
