What is delta S in the equation delta G delta H-T delta S?

Delta S represents the change in entropy of a system. In the equation delta G = delta H - T delta S, it is used to determine the contribution of entropy to the overall change in Gibbs free energy. A negative delta S value suggests a decrease in the disorder of a system.


How can one determine the delta H of a reaction?

To determine the delta H of a reaction, one can use calorimetry to measure the heat released or absorbed during the reaction. This involves measuring the temperature change of the reaction mixture and using it to calculate the heat exchanged. The delta H value represents the change in enthalpy of the reaction.


What is the value of the enthalpy change (H) when water transitions from a liquid to a gas?

The enthalpy change (H) when water transitions from a liquid to a gas is known as the heat of vaporization. This value is approximately 40.79 kJ/mol at standard conditions.


What is delta h in the equation delta g delta h - t delta s?

Delta H represents the change in enthalpy of a system. In the equation ΔG = ΔH - TΔS, it is the enthalpy change of the system. It indicates the heat absorbed or released during a reaction at constant pressure.


How is delta hf related to the delta h of the reaction?

The standard enthalpy change of a reaction (delta H) is related to the standard enthalpy of formation (delta Hf) of the products and reactants involved in the reaction by the equation: delta H = Σ(Products delta Hf) - Σ(Reactants delta Hf). This equation relates the enthalpy change of a reaction to the enthalpies of formation of the substances involved in the reaction.

How is the delta H fusion used to calculate the energy needed to melt a mass of solid?

The delta H fusion, or enthalpy of fusion, represents the amount of energy required to convert a unit mass of a solid into a liquid at its melting point without changing its temperature. To calculate the energy needed to melt a specific mass of solid, you multiply the mass of the solid by the delta H fusion value. The formula can be expressed as ( Q = m \times \Delta H_f ), where ( Q ) is the energy required, ( m ) is the mass, and ( \Delta H_f ) is the enthalpy of fusion. This calculation provides the total energy necessary to achieve the phase transition from solid to liquid.


How is the delta H fusion used to calculate volume of liquid?

It is not. The density and mass would be used to find the volume.
