B. 0.1 M.
C. 1.0 M.
D. 1.8 M.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

A.

And a) oxygen i believe
