What is the process for calculating Gibbs free energy at different temperatures?
To calculate Gibbs free energy at different temperatures, you can use the equation G H - TS, where G is the change in Gibbs free energy, H is the change in enthalpy, T is the temperature in Kelvin, and S is the change in entropy. By plugging in the values for H, S, and the temperature, you can determine the Gibbs free energy at that specific temperature.
What is the value for G at 100 K if H 27 kJmol and S 0.09 kJ(molK)?
The equation relating G, H, and S is G = H - TS, where T is the temperature in Kelvin. Plugging in the values given, G = 27 kJ/mol - 100 K * 0.09 kJ/(molK) = 27 kJ/mol - 9 kJ/mol = 18 kJ/mol. So, the value for G at 100 K is 18 kJ/mol.
What are the units of free energy and how are they determined in thermodynamics?
The units of free energy are typically measured in joules (J) or kilojoules (kJ). In thermodynamics, free energy is determined through calculations involving the change in enthalpy (H) and the change in entropy (S) of a system, using the equation G H - TS, where G is the change in free energy, H is the change in enthalpy, S is the change in entropy, and T is the temperature in Kelvin.
What is the standard free energy equation and how is it used to calculate the thermodynamic feasibility of a chemical reaction?
The standard free energy equation is G H - TS, where G is the standard free energy change, H is the standard enthalpy change, T is the temperature in Kelvin, and S is the standard entropy change. This equation is used to calculate the thermodynamic feasibility of a chemical reaction by comparing the standard free energy change to zero. If G is negative, the reaction is thermodynamically feasible and will proceed spontaneously. If G is positive, the reaction is not thermodynamically feasible and will not proceed spontaneously.
What are the units for Gibbs free energy and how are they determined in thermodynamics?
The units for Gibbs free energy are joules (J) or kilojoules (kJ). In thermodynamics, Gibbs free energy is determined by calculating the difference between the enthalpy (H) and the product of the temperature (T) and the entropy (S), using the equation: G H - TS.
What is S in the equation G H-TS?
In the equation GH-TS, S represents the entropy of the system. Entropy is a measure of the amount of disorder or randomness in a system.
What is T in the equation G equals H TS?
The temperature in kelvins at which the reaction is happening
What is the T in the equation g h-t s?
The change in entropy between products and reactants in a reaction.
What could make Delta become negative at a given enthalpy and entropy?
The equation for ∆G is ∆G = ∆H - T∆S H is enthalpy and S is entropySo, ∆G is negative if T∆S is greater than ∆H
The equation G equals H-TS predicts that?
the Gibbs free energy (G) of a system is equal to the enthalpy (H) minus the temperature (T) multiplied by the entropy (S). This equation is used to determine whether a reaction is spontaneous (ΔG < 0) or non-spontaneous (ΔG > 0) at a given temperature.
What is the relationship between entropy and free energy in thermodynamics?
In thermodynamics, entropy and free energy are related through the equation G H - TS, where G is the change in free energy, H is the change in enthalpy, T is the temperature in Kelvin, and S is the change in entropy. This equation shows that the change in free energy is influenced by both the change in enthalpy and the change in entropy.
What is h in equation g h -t s?
The change in entropy between products and reactants in a reaction.

What is S in the equation G H T S?
The change in entropy between products and reactants in a reaction.
What is s in the equation gh-ts?
Without an equality sign the given expression can't be considered to be an equation. But if you mean: gh = ts then s = gh/t
