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?
A catalyst does not affect the enthalpy change of a reaction. It speeds up the reaction by providing an alternative pathway with a lower activation energy, allowing the reaction to proceed faster. The overall enthalpy change (ΔH) remains the same with or without a catalyst.
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.
What is a correct description of enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
How is enthalpy related to the spontaneously of a reaction?
H < 0 contributes to spontaneity.
How is enthalpy related to spontaneity of a reaction?
S > 0 contributes to spontaneity.
How does temperature affect the spontaneity of a reaction?
Increasing the temperature makes a reaction spontaneous in some situations.
How will temperature affect the spontaneity of reaction with positive H and S?
A high temperature will make it spontaneous.
How does temperature affect spontaneity?
If H and S have the same sign, the temperature will determine spontaneity.
How does the presence of a catalyst affect the enthalpy change of a reaction?
A catalyst does not affect the enthalpy change of a reaction. It speeds up the reaction by providing an alternative pathway with a lower activation energy, allowing the reaction to proceed faster. The overall enthalpy change (ΔH) remains the same with or without a catalyst.

How does the Gibbs free energy predict spontaneity?
It tells if the reaction will process spontaneously or not
