Answer 1

Answer #1

Arrange the following molecules in order of increasing average molecular speed. Ar at 371 K, CH4 at 430K, N2 at 371 K, Ar at

Explanation :

molecular speed = sqrt (3 RT / M)

temperature is directly proportional to average molecular speed.

so temperature is increases , then molecular speed also increase.

molar mass increases, then molecular speed decreases
