Question
For the melting of NaCl heat required is 7.26 kcal mol-1 and ΔS increases by 6.73 cal mol-1 k-1 . The melting point of the salt is 805.75 ° C. HOW???
Read 1 Solution.
dS FUSION = dH / T MELTING PT
T= dH/dS = 7.26 X 1000 / 6.73 K ( dH Is given in kilocal /mol so remember to of conversion) = 1078.75 K = (1078.25- 273)OC=805.750C
