Question

Which of the following statements regarding Gibb's energy change is correct? (A) If Δ G is negative (< 0), the process is non-spontaneous (B) If Δ G is positive (> 0), the process is spontaneous (C) If Δ G is negative (< 0), the process is spontaneous (D) If Δ G is positive (> 0), the process is in equilibrium

The energy available for a system at some conditions and by which useful work can be done is Gibb's energy (G).

G = H - TS

For spontaneous process,

Δ G < 0

For non-spontaneous process,

Δ G > 0

For equilibrium process,

Δ G = 0

Q. Which of the following statements regarding Gibb's energy change is correct?

If $Δ G$ is negative $(< 0)$ , the process is non-spontaneous

If $Δ G$ is positive $(> 0)$ , the process is spontaneous

If $Δ G$ is negative $(< 0)$ , the process is spontaneous

If $Δ G$ is positive $(> 0)$ , the process is in equilibrium

$G = H - TS$
For spontaneous process, $Δ G < 0$
For non-spontaneous process, $Δ G > 0$
