    A chemical reaction occuring in open vessel is observed by student. He was observing the reaction from 3 h. He has not notice any change. Suddenly his friend comes and increases the temperature. He suddenly get the desired product. What will be the value of Gibbs free energy change of the reaction during those 3 h?.

    A)  > 0                             

    B)  < 0

    C)  = 0                             

    D)  \[\ne \,\,0\]
