How is enthalpy related to the spontaneously of a reaction?
H < 0 contributes to spontaneity.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
Predict whether the changes in enthalpy entropy and free energy will be positive or negative for the freezing of water and explain your predictions How does temperature affect the spontaneity?
Enthalpy- positive Entropy- decreasing Free energy- negative
How will the temperature affect the spontaneity of a reaction with positive h and s?
A high temperature will make it spontaneous.
What is a correct description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
How is enthalpy related to spontaneity of a reaction?
S > 0 contributes to spontaneity.

What kind of changes contribute to spontaneity?
An increase in entropy.
How will temperature affect the spontaneity of reaction with positive H and S?
A high temperature will make it spontaneous.
How will the temperature affect the spontaneity of a reaction with positive h and s?
A high temperature will make it spontaneous.
What does the enthaply of reaction measure?
The enthalpy of reaction is the change of the system enthalpy after a chemical reaction.
What is the description of the enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is the description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
How does temperature affect the spontaneity of a reaction?
Increasing the temperature makes a reaction spontaneous in some situations.
What is a correct description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
