O GASES Interpreting a graph of molecular speed distribution Here is a graph of the probability of an atom moving with a particular speed, for a sample of helium gas at-6.?. probability speed (m/s) Use this graph to answer the following questions. Round each of your answers to the nearest m/s Note: your answers must be within 125 m/s of the exact answers to be graded correct. this sample? What higher speed is only half as likely as the most likely speed? DF what higher speed is only 10% as likely as

Explanation / Answer

From the plot of speed distribution we can answer the following;

i) The most likely speed of He atom = 1000m/s ( approximately)

As the probability is maximum over there.

ii) The higher speed only half of most likely speed = 1750m/s (approximately)

Here the probability is 50% of the maximum probability.

iii) The higher speed only 10% of the most likely speed = 2250m/s (aprroximately)

Here the probability is 10% of the maximum probability.
