Identify the correct statement for the change in Gibbs energy $(\Delta G_{\text{system}})$ for a system at constant temperature and pressure.

  • A
    If $\Delta G_{\text{system}} > 0$,the process is spontaneous.
  • B
    If $\Delta G_{\text{system}} = 0$,the system is in equilibrium.
  • C
    If $\Delta G_{\text{system}} = 0$,the system moves in a specific direction.
  • D
    If $\Delta G_{\text{system}} < 0$,the process is non-spontaneous.
