`Au(s) hArr Au (l)`
above mentioned equilibrium is fovoured at

A

High pressure low temperature

B

High pressure high temperature

C

Low pressure, high temperature

D

Low pressure, low temperature

Text Solution

Verified by Experts

The correct Answer is:
C

`Au(s) + heat rarr Au(l)`
There is an increase in volume in the forward direction, hence the melting is favoured at low pressure.
Since melting is an endothermic process, it is favoured at high temperature
