Worked Solution & Example Answer:The diagram shows the Maxwell-Boltzmann distribution of molecular energies in a gas at two different temperatures - AQA - A-Level Chemistry - Question 16 - 2017 - Paper 3
Step 1
Which letter represents the most probable energy of the molecules at the higher temperature?
Answer
To determine which letter represents the most probable energy of the molecules at the higher temperature in the Maxwell-Boltzmann distribution, we must analyze the graph provided.
In the diagram, as temperature increases, the peak of the distribution shifts to the right, indicating that molecules have higher energies at higher temperatures. Therefore, the most probable energy at the higher temperature is represented by the point at the peak of the curve corresponding to the higher temperature.
In this case, the letter 'D' represents this peak. Thus, the answer to the question is:
D
