Question

α and β forms of sulphur are at equilibrium at a temperature known as ______.

Options

• Critical temperature 

• Transition temperature 

• Boyle's temperature

• Inversion temperature

Answer 1

α and β forms of sulphur are at equilibrium at a temperature known as Transition temperature.

Explanation:

The transition temperature is the level at which both sulphur species coexist.

\[\ce{\alpha{ - } sulphur <=>[> 369 K][< 369 K] \beta { - } sulphur}\]
