Question

label the image with the options given below
energy diagram
potential energy (kj)
reaction time (min)
activation energy energy of the reactants energy of the products
change in energy of the reaction total energy of the reaction

Explanation:

• Energy of the reactants: The initial energy level at the start of the reaction (horizontal line at the beginning of the curve).
• Activation energy: The energy difference between the reactants and the peak of the curve (the energy barrier that needs to be overcome for the reaction to proceed).
• Energy of the products: The final energy level at the end of the reaction (horizontal line at the end of the curve).
• Change in energy of the reaction: The difference in energy between the reactants and the products.
• Total energy of the reaction: This term is a bit ambiguous, but if we consider it as the overall energy profile (sum of all energy aspects in the diagram conceptually), it relates to the entire potential - energy vs reaction - time plot.

Answer:

• Energy of the reactants: The starting horizontal line (e.g., if we assume the first horizontal segment at a certain \(y\) - value on the potential energy axis).
• Activation energy: The vertical distance from the reactants' energy level to the peak of the curve.
• Energy of the products: The ending horizontal line (e.g., the last horizontal segment at a certain \(y\) - value on the potential energy axis).
• Change in energy of the reaction: The vertical distance between the reactants' and products' energy levels.
• Total energy of the reaction: The entire potential - energy vs reaction - time graph (representing all energy states during the reaction).
