Answer Key for Energy Curve Worksheet
This answer key provides the correct answers and explanations for the Energy Curve Worksheet. Students can use this key to check their work and understand the concepts related to energy curves.
Question 1: The graph shows the energy changes of a reaction over time. Identify the initial energy, the activated complex, and the final energy.
- The initial energy is the energy of the reactants before the reaction takes place.
- The activated complex (also known as the transition state) is the highest point on the energy curve, where the reactants are in an unstable state.
- The final energy is the energy of the products after the reaction is complete.
Question 2: What does the height of the energy curve represent?
The height of the energy curve represents the energy difference between the reactants and the activated complex. It indicates the amount of energy required for the reaction to proceed.
Question 3: Explain how a catalyst affects the energy curve.
A catalyst lowers the activation energy of a reaction, which means it reduces the height of the energy curve. This allows the reaction to occur more easily and at a faster rate. The catalyst provides an alternative reaction pathway with a lower energy barrier.
Question 4: How does temperature affect the energy curve?
Increasing the temperature increases the kinetic energy of the particles, which leads to more frequent and energetic collisions. This results in a higher probability of successful collisions and a lower activation energy. Therefore, an increase in temperature shifts the energy curve to the left, indicating a faster reaction rate.
Question 5: What is the relationship between the activation energy and the reaction rate?
The activation energy is inversely related to the reaction rate. A higher activation energy requires more energy for the reaction to occur, resulting in a slower rate. Conversely, a lower activation energy allows the reaction to occur more easily and at a faster rate.
