Construct a plot of ln(K_sp) vs 1T using your data from the above table. From the graph determine the slope and evaluate H. For the R-value, use 8.314 Jmol¹K¹.

(i) slope = H/R

(ii) H Jmol¹

(b) From your plot of ln(K_sp) vs 1T, find the y-intercept to determine S.

(i)SR = ln(K_sp) + HRT

(ii) S (Use the data you entered for 25 mL to solve for S.)

Jmol¹K¹

c) Using your experimentally determined H and S, determine the G at 60.0C.
