For the melting of nacl heat required is 7.26 kcal mol-1 and S increases by 6.73cal mol-1K-1. The melting point of salt is
Answered by admin @
dS FUSION = dH / T MELTING
T= dH/dS = 7.26 X 1000 / 6.73 T=1078.75 Kelvin ( dH Is given in kilocal /mol so remember to multiply it with 1000 for cal mol^-2 k^-1)
For converting it to celcius (1078.25- 273)OC=805.750 °C
