Calculating ΔS universe for deposition of iodine QUESTION

  1. May 22, 2012 #1
    Use the data below to calculate ΔSuniverse for the deposition of iodine at 298 K.

    ΔfHo (kJ mol–1), ΔS (J K–1 mol–1)
    I2(s) 0.00 , 116
    I2(g) 62 , 261

    a) –353. J K–1 mol–1
    b) –63.1 J K–1 mol–1
    c) +63.1 J K–1 mol–1
    d) +353 J K–1 mol–1
    e) +377 J K–1 mol–1

    ok my working out,




    im not sure where to go from here

    Also i know that ΔSuniverse=ΔSsystem+ΔSsurroun

    Any suggestions. Much apreciated
