Ha is a monoprotic weak acid. if a 0.015 m ha solution is 2.5% dissociated (or ionized), what is the acid dissociation constant (ionization constant)?

Get on mathpapa is shows you the answer and how to explain it

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.
