24. The vapor pressure of solid I2 is measured (in bar) over the temperature range 0-55 °C. The natural logarithms of these vapor pressures are plotted as a function of the reciprocal of the absolute temperature as shown below. What is the standard enthalpy of sublimation (AH° subl) of I₂(s)? In(vapor pressure) -5.0 -6.0 -7.0 -8.0 -9.0 -10.0 y = 17.44-7527x -11.0- 0.0030 0.0031 0.0032 0.0033 0.0034 0.0035 0.0036 0.0037 1/T, K-¹ (A) 7.53 kJ mol-¹ (C) 19.4 kJ mol-¹ (B) 17.4 kJ mol-¹ (D) 62.6 kJ mol-¹
