Question

Write the correct condition for spontaneity in terms of Gibbs energy.

Hint:

A process is spontaneous if the change in Gibbs free energy, \( \Delta G \), is negative.

Answer 1

The condition for spontaneity of a process in terms of Gibbs free energy (\( G \)) is given by: \[ \Delta G = \Delta H - T\Delta S \] For a process to be spontaneous, the change in Gibbs free energy must be negative: \[ \Delta G < 0 \] Thus, the correct condition for spontaneity is: \[ \Delta G < 0 \]
