NEET AIPMT SOLVED PAPER SCREENING 2006

  • 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 process is spontaneous       

    B)                   If \[\Delta {{G}_{system}}=0\], the system has attained equilibrium

    C)                   If \[\Delta {{G}_{system}}=0\], the system is still moving in a particular direction

    D)                   If \[\Delta {{G}_{system}}<0\], the process is not spontaneous

    Correct Answer: B

    Solution :

                    If the Gibbs free energy for a system \[(\Delta {{G}_{system}})\] is equal to zero, then system is present in equilibrium at a constant temperature and pressure.
