Why is a reaction spontaneous when Delta G < 0? - Socratic
2018年1月14日 · If the initial state of a reaction proceeds to give a decrease in G, then the reaction is spontaneous. But that means (dG)/ (d xi) < 0 and corresponds to Delta_rG < 0. …
Does ΔG = 0 at equilibrium? - Socratic
2014年10月31日 · Yes. DeltaG=-lnK_c If DeltaG=0 then K_c=1 So, in free energy terms we have equilibrium.
In an exergonic reaction, what is the DeltaG? | Socratic
2016年12月17日 · DeltaG is negative, which means that the reaction is spontaneous in the forward direction. As the chemical reaction proceeds, the reactants are being converted into …
In a reaction A -> B with Delta G < 0, why is there ... - Socratic
2018年2月14日 · Equilibrium is the balance point. Whether a reaction proceeds in one way or not is the thermodynamics. But before the kinetics finish their job the overall equilibrium MUST be …
What is K if DeltaG^@ = -18.0 kJ for a reaction at 25 degrees C?
2017年4月16日 · What is K if ΔG∘ = -18.0 kJ for a reaction at 25 degrees C?
Galvanic cell run at 25° C: calculate - Socratic

How do you calculate DeltaG for a reaction from DeltaH and …
2017年4月16日 · Delta"G"=Delta"H"^@-"T"Delta"S" In order to calculate the free energy for a reaction, the above equation should be used. Thus, the temperature of the experiment, in …
What conditions make DeltaG always positive? | Socratic
2017年9月9日 · If ΔH is positive and ΔS is negative If reaction is endothermic (ΔH is +ve), and entropy decreases (ΔS is -ve), then ΔG must be +ve and reaction is reactant-favored in the …
Are chemical reactions always spontaneous when - Socratic
2016年7月18日 · No. A reaction cannot be spontaneous under these conditions unless Temperature is low enough. The equation for spontaneity is DeltaG=DeltaH-TDeltaS A …
How does free energy change in an exergonic reaction? - Socratic
2014年9月28日 · In an exergonic reaction the free energy change DeltaG is negative. This means that such a reaction will be spontaneous.
