Which of the following is NOT true for ΔGrxn?
A.) If ΔG°rxn > 0, the reaction is spontaneous in the forward direction.
B.) If Q = 1, then ΔGrxn = ΔG°rxn.If ΔG°rxn = 0, the reaction is spontaneous in the reverse direction.
C.) If ΔG°rxn > 0, the reaction is spontaneous in the reverse direction.
D.) Under equilibrium conditions, ΔGrxn=0.

I think C and D are true; A and B are not true.
Thank you DrBob222, could you possibly elaborate why C or D could be correct? (I initially thought C, but I'm not so sure now.)
typo: *not be correct
C. If dGrxn > 0 that means it is + some number so dGrxn for the reverse reaction will be - and a negative dG means spontaneity.
D. When dG = 0 the system is at equilibrium. (because the only other possibilities are + and -; if + it goes in the reverse and if - it is spontaneous as written).
D. When dG = 0 the system is at equilibrium. (because the only other possibilities are + and -; if + it goes in the reverse and if - it is spontaneous as written).
