{change in entropy when solid NaCl melts}
« on: September 05, 2016, 06:20:38 PM »
Calculate the change in entropy when solid NaCl melts at its melting point of 800. oC given the enthalpy of fusion for NaCl = 30.2 kJ/mol

plz>>> answer with doing calculation

thank you!

It is very simple ...please check your text book for the relation in entropy ,temperature and enthalpy  and plugged in the values...
