How is the speed of chemical reaction related to the spontaneity of the reaction?

The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.


How will temperature affect the spontaneity of reaction with positive H and S?

A high temperature will make it spontaneous.


How is Hess's law used to measure enthalpy of a desired reaction?

... Intermediate equations with known enthalpies are added together.


How do you calculate the enthalpy change of a reaction?

To calculate the enthalpy change of a reaction, subtract the total enthalpy of the reactants from the total enthalpy of the products. This difference represents the enthalpy change of the reaction.


What is the significance of the Gibbs energy equation in determining the spontaneity of a chemical reaction?

The Gibbs energy equation helps determine if a chemical reaction will occur spontaneously by considering the change in enthalpy and entropy of the system. If the Gibbs energy is negative, the reaction is spontaneous.


Is Delta S is the change in enthalpy a measure of randomness?

No, ΔS (change in entropy) and ΔH (change in enthalpy) are not measurements of randomness. Entropy is a measure of the disorder or randomness in a system, while enthalpy is a measure of the heat energy of a system. The change in entropy and enthalpy can be related in chemical reactions to determine the overall spontaneity of the process.
