Arrange the following in order of increasing entropy, from smallest to largest value.

1.00 g Br2 (gas, 331.9 K, 0.10 atm) 

1.00 g Br2 (gas, 331.9 K, 1.00 atm) 

1.00 g Br atoms (gas 331.9 K, 0.10 atm) 

1.00 g Br2 (liquid, 331.9 K, 1.00 atm) 

(Answers for each can be 1-4)

Decide which is the least random set of conditions.

 

check_circleExpert Solution
Step 1

Entropy is a measure of randomness of particles. The increasing order of randomness of particles in different phases of matter is:

Solid < Liquid < Gas

Step 2

Thus, 1 g Br2 (liquid) is the least random of all the mentioned options.

Step 3

All other options have gaseous particles. The atoms are more random than the molecules because atoms are not bonded and are ...
