Question

hello, it is about entropy change over temparature range. thank you for your help

Use the data given in the table below to draw the S(T)-diagram for the heating up of ethanol from 100 K to 150 °C (at 1 atm). At atmospheric pressure, ethanol melts at - 114 °C and evaporates at 351 K. Phase (transition) S s→l I l→g g Cp / J mol-¹ K-1 111 112 78 Atrs H I kJ mol-1 4.9 42.32 Hint: For the X-axis, use approximately the given temperatures. On the Y-axis, consider relative changes but do not calculate exact S values.
