How does Gibbs free energy predict spontaneous?
If G < 0, the reaction is spontaneous.
What does the gibbs free energy predict?
It predicts whether or not a reaction will be spontaneous.
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
If the sign of H is and the sign of S is then the magnitude of T S must be than the magnitude of dH for the reaction to be spontaneous The Gibbs free energy equation is G?
If the sign of ΔH is _______ and the sign of ΔS is _______ , then the magnitude of TΔS must be ________ than the magnitude of ΔH for the reaction to be spontaneous. The Gibbs free energy equation is ΔG = ΔH - TΔS. negative; negative; less
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 a negative Gibbs free-energy value an indication of?
Spontaneous reaction
How does Gibbs free energy predict spontaneous?
If G < 0, the reaction is spontaneous.
What does Gibbs energy predict?
It predicts whether or not a reaction will be spontaneous.
According to the Gibbs free energy equation G H - TS when is a reaction always spontaneous?
when H is negative and S is positive
What does the gibbs free energy predict?

What happens in an endergonic reaction?
An endergonic reaction is a chemical reaction in which the standard change in free energy is positive.
What is true about the numerical value of the Gibbs free-energy change for a spontaneous reaction?
B
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.
Is polymerization endothermic or exothermic?
Exothermic, because the reaction enthalpy must be negative. With polymerization, the entropy decreases. The Gibbs energy has to be negative. Thus negative reaction enthalpy. Gibbs energy = reaction enthalpy - temperature*entropy
