Gibbs energy

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

Identify the correct statement for change of Gibb's energy for a system (Delta G_("system")) at constant temeprature and pressure:

Select correct statements: S_(1) : For every chemical reaction at equilibrium , standard gibbs energy of reaction is zero S_(2) : At constant temperature and pressure , chemical reactions are spontaneous in the direction of decreasing gibbs energy. S_(3) : Spontancity is related to change in entropy if universe.
