• # question_answer Identify the correct statement for change of Gibbs energy for a system$(\Delta {{G}_{system}})$ at constant temperature and pressure: A)  if $\Delta {{G}_{system}}=0,$ the system is still moving in a particular directionB)  if$\Delta {{G}_{system}}=-ve,$not spontaneousC)  if $\Delta {{G}_{system}}=+ve,$the Process is spontaneousD)  if $\Delta {{G}_{system}}=0,$the system has attained equilibrium

$\Delta {{G}_{system}}=-ve,$the system is spontaneous;$\Delta {{G}_{system}}=0,$the system has attained equilibrium $\Delta G=+ve,$the system is nonspontaneous.
