For binary phase diagram Gibbs phase rule may be given as _______

Question

RRB Paper · Accepted Answer

A binary phase diagram shows the phases formed in differing mixtures of two elements over a range of temperatures. The binary phase diagrams are usually drawn at atmospheric pressure, showing variations in temperature and composition only. Pressure changes often produce no significant effect on the equilibrium and, therefore, it is customary to ignore the pressure variable and the vapor phase. The Gibbs phase rule for binary phase diagram F = C – P + 1 gives the relationship between the number of phases p and components c in a given alloy under equilibrium conditions at constant pressure.

For binary phase diagram Gibbs phase rule may be given as _______

F = C + P + 2

F = C ? P + 2

F = C ? P + 1

F = C + P ? 1

The correct answer is `No. 3: F = C ? P + 1`
