: Because some particles move much faster, the curve must stretch horizontally. To keep the total area (particle count) the same, the peak must drop vertically to compensate for this horizontal stretching. Khan Academy Summary of Key Relationships Higher Temperature : Curve becomes lower and wider; peak shifts right. Higher Molar Mass : Curve becomes taller and narrower; peak shifts left. Adding a Catalyst : Curve stays the same; the cap E sub a threshold shifts left. siebertscience.com step-by-step guide
of the curve (the position of the peak and the width of the distribution) remains exactly the same because temperature, which determines the average speed, has not changed. However, the area under the curve If you need a usable set of answers
A common extension task is to identify or calculate the three different measures of "average" speed. On a graph, they always appear in this order from left to right: The peak of the curve. Average Speed ( vavgv sub a v g end-sub which determines the average speed
