## What is the formula for an endothermic reaction?

The general equation for an endothermic reaction is: Reactants + Energy → Products. Note: ΔH represents the change in energy. In endothermic reactions, the temperature of the products is typically lower than the temperature of the reactants.

What is an endothermic reaction graph?

It is possible to represent the endothermic reaction in the form of a graph called the energy diagram. The potential energy of the reaction is plotted along the vertical axis, and time is plotted along the horizontal axis. This graph shows the change in energy as the reaction progresses from reactants to products.

What is true about a potential energy diagram for an endothermic reaction?

The energy value remains the same throughout the diagram. The graph starts at a lower energy value and ends at a higher energy value. The potential energy of the products is equal to the potential energy of the reactants. giosingh2121 is waiting for your help.

### What is the example of endothermic reaction?

Melting ice cubes. Melting solid salts. Evaporating liquid water. Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.

What are three examples of exothermic reactions?

Here are some of the examples of exothermic reaction:

• Making of an ice cube. Making ice cube is a process of liquid changing its state to solid.
• Snow formation in clouds.
• Burning of a candle.
• Rusting of iron.
• Burning of sugar.
• Formation of ion pairs.
• Reaction of Strong acid and Water.
• Water and calcium chloride.

What is potential energy diagram?

A potential energy diagram shows the change in potential energy of a system as reactants are converted into products. Potential energy diagrams for endothermic and exothermic reactions are described.

## What does a graph represent an endothermic reaction?

Question Answer Does the graph represent an endothermic Exothermic Determine the heat of reaction, D H, for -20kJ Determine the activation energy, Ea for +60kJ What is the energy of the activated comp 100kJ

How does potential energy decrease in exothermic reaction?

The total potential energy of the system decreases for the exothermic reaction as the system releases energy to the surroundings. Figure 1. A potential energy diagram shows the total potential energy of a reacting system as the reaction proceeds.

How are energy changes shown in a potential diagram?

The energy changes that occur during a chemical reaction can be shown in a diagram called a potential energy diagram, or sometimes called a reaction progress curve. A potential energy diagram shows the change in potential energy of a system as reactants are converted into products.

### When does potential energy change in a chemical reaction?

A potential energy diagram plots the change in potential energy that occurs during a chemical reaction. This first video takes you through all the basic parts of the PE diagram. The diagram represents the potential energy changes when a cold pack is activated.
