The following data is known about the melting of a compoun AB. `Delta H = 9.2 kJ mol^(-1), Delta S = 0.008 kJ K^(-1) mol^(-1)`. Its melting point is :

A

736 K

B

1050 K

C

1150 K

D

`1150^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
C
At melting point, `DeltaG= DeltaH - T Delta S=0`
or `Delta H = T Delta S`
`or T= (Delta H)/(Delta S)`
`=(9.2)/(0.008) = 1150K`
