When ΔG ̊=0, the system is at equilibrium and both the forward
and reverse reaction are proceeding at equal rates. This is the
case during phase transitions. Consider the phase transition and
the data shown for BCl3 below. Calculate the boiling point (in ̊C)
for BCl3. BCl3(l) ⇄ BCl3(g) Hf ̊ (kJ/mole) S ̊ (J/mol∙K) BCl3(l)

Is it possible for a reaction to have a large equilibrium constant but small forward and reverse rate constants? Choose one - A. No, the equilibrium constant and rate constant are both determined by the same thermodynamic parameters. B. Yes, the equilibrium constant is determined by the ratio of the forward and reverse rate constants, not the absolute value of those rates C. No, a large equilibrium constant means that the rate constants must also be large D. Yes, the...
