What does the gibbs free energy predict?
It predicts whether or not a reaction will be spontaneous.
How does Gibbs free predict spontaneity?
If G < 0, the reaction is spontaneous.
Is the Gibbs free energy negative in the spontaneous reaction?
Yes, as long as the entropy of the universe increases.
If dissolving calcium chloride in water is spontaneous what is the sign?
If dissolving calcium chloride in water is spontaneous, the sign of ΔG (Gibbs free energy) is negative.
What is the name and symbol of the single thermodynamic quantity which determines whether or not a reaction is spontaneous?
Gibbs free energy -- symbol G. If the change in Gibbs free energy for a reaction is negative, the reaction is spontaneous. If it is zero, you are at equilibrium. If it is positive, the reaction is NOT spontaneous.G ≡ H -TS (or in another useful form dG = dH -TdS)whereH is enthalpyT is absolute temperatureS is entropy

What is a negative Gibbs free-energy value an indication of?
Spontaneous reaction
What is Gibbs Free energy?
The usable energy released or absorbed by a reaction.
What is true about the numerical value of the Gibbs free-energy change for a spontaneous reaction?
B
Is the Gibbs free energy negative in the spontaneous reaction?
Yes, as long as the entropy of the universe increases.
Using the Gibbs free energy equation what is the temperature range for which the oxidation of lead is spontaneous?
The reaction is spontaneous below 554.8/0.1975 K.
According to the Gibbs free energy equation what is the temperature range for which the formation of liquid bromine is spontaneous?
The reaction is spontaneous below 743 K.
Use the gibbs free energy equation shown below to determine the temperature for which the decomposition of KClO4 is spontaneous?
The reaction is spontaneous above 371 K.
How does the Gibbs free energy predict spontaneity?
It tells if the reaction will process spontaneously or not
Using the Gibbs free energy equation what is the temperature in degrees celsius above which decompostion of KCIO4 is spontaneous?
-51 - -50.5
How can you decide whether a chemical process is spontaneous?
Whether or not a chemical process is spontaneous is determined by a variable named the Gibbs' free energy, or just Gibbs' energy, given by the formula G = H - TS, where G is the Gibbs' energy, H is enthalpy, T is temperature and S is entropy. A negative G implies that the chemical process is spontaneous and will occur by itself, and a positive G implies that energy is required to make the reaction occur.
