Identify the correct statement for change of Gibb's energy for a system ($\Delta $Gsystem) at constant temperature and pressure.
If $\Delta $Gsystem < 0, the process is not spontaneous.
If $\Delta $Gsystem > 0, the process is spontaneous.
If $\Delta $Gsystem = 0, the system has attained equilibrium.
If $\Delta $Gsystem = 0, the system is till moving in a particular direction.
