Start up energy of a chemical reaction?
The activation energy is the minimum amount of energy required to initiate a chemical reaction. It helps to break the existing bonds in reactant molecules and start the formation of new bonds in the product molecules. Lowering the activation energy can increase the reaction rate.
Activation energy to break chemical bonds is provided by?
Activation energy to break chemical bonds is provided by an external energy source, typically in the form of heat or light. This additional energy helps overcome the energy barrier required to break the existing bonds and initiate a chemical reaction.
What is the function of sunlight in the reaction?
Sunlight provides the energy needed to drive the reaction and activate the molecules involved in the process. It helps break down reactants and form products by providing the necessary energy for chemical reactions to occur.
Why was it necessary to heat the text tube in order for a chemical reaction to occur?
Heating the test tube provides the reactant molecules with more kinetic energy, increasing the likelihood of successful collisions that lead to a reaction. This helps break bonds and activate reactants, allowing the reaction to happen at a faster rate.
What is the effect of the addition of a catalyst on the rate of a chemical reaction?
A catalyst increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy. This allows for more reactant molecules to overcome the energy barrier and form products more quickly, without being consumed in the process.
What chemical reaction helps break down food to get energy required?
This is the digestion process.

What is the energy needed to break existing chemical bonds during the initiation of a chemical reaction?
The energy needed to break an existing chemical bond is called activation energy, also written as EaActivation energy can be decreased with the help of a catalyst, which helps to facilitate chemical reactions.

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.
What is the relationship between the heat of reaction and a chemical reaction?
The heat of reaction is the amount of heat energy released or absorbed during a chemical reaction. It is a measure of the reaction's energy change. The relationship between the heat of reaction and a chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat). This information helps us understand the energy changes that occur during the reaction.
What is the significance of the reaction coordinate diagram in understanding the energy changes and progress of a chemical reaction?
The reaction coordinate diagram is important because it helps us visualize and understand how energy changes during a chemical reaction. It shows the progress of the reaction from start to finish, including the energy levels of the reactants, transition states, and products. This diagram helps us predict the feasibility and speed of a reaction, as well as the overall energy changes involved.
What role does the reaction coordinate diagram play in identifying the rate determining step of a chemical reaction?
The reaction coordinate diagram helps identify the rate determining step of a chemical reaction by showing the energy changes as the reaction progresses. The highest energy point on the diagram corresponds to the rate determining step, where the activation energy is highest.
What is the significance of the Gibbs free energy diagram in understanding the thermodynamic feasibility of a chemical reaction?
The Gibbs free energy diagram helps determine if a chemical reaction is likely to occur by showing the energy changes involved. If the overall change in Gibbs free energy is negative, the reaction is thermodynamically feasible and likely to happen.
