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

A

High pressure, lowtemperature

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" hArr Au(l)`
(i) There is an increase in volume in the forward direction, hence the melting is favoured at low pressure.
(ii) Since melting is an endothermic process, it is favoured at high temperature.
