WebJan 15, 2024 · Again, because ln(χi) < 0, then ΔGmix < 0 implying that mixing is always a spontaneous process for an ideal solution. This is true for gases. But for many combinations of liquids or solids, the strong intermolecular forces may make mixing unfavorable (for example in the case of vegetable oil and water). WebQuestion For a spontaneous reaction the ΔG, equilibrium constant K and E 0cell will be respectively: A −ve,>1,−ve B −ve,<1,−ve C +ve,>1,−ve D −ve,>1,+ve Hard Solution …

WebA reaction will be spontaneous only at high temperatures if both ΔH and ΔS are positive. For a reaction in which ΔH= 199.5 kJ/mol and ΔS= 476 J/K∙mol, determine the temperature (in °C) above which the reaction is spontaneous. - The temperature that divides high from low is the temperature at which ΔH= TΔS (ΔG= 0). WebFeb 19, 2015 · The term "reversible process" does not mean that $\Delta G = 0$. Reversible process is an imaginary or idealized process which occurs in infinitesimally small steps, such that the system very close to equilibrium throughout the process. However, the infinite number of infinitesimally small steps would add up to an finite change. c1インアクチベーター
