You have a 2.0 Molar solution of an unknown acid, “HX”. Given the (25°C) thermodynamic data below, calculate Keq given that Keq = exp.[-ΔG/RT] and R is the gas constant 8.314 J/mol K
Another useful equation : ΔG = ΔH - TΔS
HX —> H+ + X- all aqueous
Enthapies of formation Entropy of formation
In KJ/mole in J/mole K
HX 200 300
H+ 10 0
X- 250 175
Do you have to multiply the enthaply and entropy values by 2 because it is a 2.0 molar solution when calculating delta G and K eq? If you do, would the answer be incorrect ?
