Oxygen (O₂) is necessary for cellular respiration; it must be transported from the lungs to tissues through the bloodstream. However, O₂ is not very soluble in water. The Keq of oxygen dissolving at 300.0 K is 7.64 x 10⁻⁴. Calculate the ∆G(dissolve) for oxygen at 300.0 K, in kJ/mol.
a) 35.74
b) -35.74
c) 25.85
d) -25.85
