Saturated fatty acids are the type of fatty acids where all of them have single bonds. Their name comes from the fact that usually the second bond they have will be broken up and because of this each half of the bond can be saturated (attached to) with a hydrogen atom that can be available in near vicinity. It is worth noting that thhe fatty acids of fish and plants are mostly unsaturated (either mono-unsaturated or poly-unsaturated) while the fatty acids of animals are mostly saturated.

The values of enthalpy change, entropy change and temperature all determine the spontenity of a reaction.
<h3>What is a sponteanous reaction?</h3>
A sponteanous reaction is one which has the change in free energy as negative. We know that ΔG = ΔH - TΔS. The spontenity of a reaction depends on;
i. enthalpy change
ii. entropy change
iii. temperature
Since the values in the qestion are not given, the question is incomplete and we can not obtain a numerical value in order to decide the sponteanity of the reaction.

The first dissociation for H2X:
H2X +H2O ↔ HX + H3O
initial 0.15 0 0
change -X +X +X
at equlibrium 0.15-X X X
because Ka1 is small we can assume neglect x in H2X concentration
Ka1 = [HX][H3O]/[H2X]
4.5x10^-6 =( X )(X) / (0.15)
X = √(4.5x10^-6*0.15)
∴X = 8.2 x 10-4 m
∴[HX] & [H3O] = 8.2x10^-4
the second dissociation of H2X
HX + H2O↔ X^2 + H3O
8.2x10^-4 Y 8.2x10^-4
Ka2 for Hx = 1.2x10^-11
Ka2 = [X2][H3O]/[HX]
1.2x10^-11= y (8.2x10^-4)*(8.2x10^-4)
∴y = 1.78x10^-5
∴[X^2] = 1.78x10^-5 m
