I have a question about gibbs free energy vs gibbs standard freeenergy.

We know that at equilibrium deltaG = 0 and Q = K, and deltaGstandard is a non-zero value.
But I don't understand. If I want to see if a reaction is atequilibrium then I have to calculate the deltaG standard first,before I can calculate deltaG to see if its value is 0 or not.
And everytime I do that, the deltaG standard equals 0 understandard conditions. That dosen't makes sense comparing to thestatement about that deltaG standard is a non-zero value atequilibrium.
Why is my deltaG standard always zero? The relationship betweenthem will be: deltaG=deltaG standard at equilibrium????
Help me

This question is related to Thermodynamics The equilibrium for any reaction is indicated by the value of Gibbs free energy change At equilibrium G 0 and it is called the equilibrium of spontaneity G 0 means that the reaction rate is constant both for forward and backward reaction Gibbs free energy is a measure of thermodynamic potential that See Answer
