Question

For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour. System Change ?S A mixture of nitrogen (N?) gas and carbon dioxide (CO?) gas at 3 atm and -3°C An additional 2.0 L of pure CO? gas is added to the mixture, with the pressure kept constant at 3 atm ? ?S < 0 ? ?S = 0 ? ?S > 0 ? not enough information A solution made of ammonium chloride (NH?Cl) in water, at 83°C 50 mL of pure water is added to the solution ? ?S < 0 ? ?S = 0 ? ?S > 0 ? not enough information 300 mL of a solution made from ammonium chloride (NH?Cl) dissolved in water. 0.5 g of NH?Cl crystallizes out of the solution, without changing the temperature ? ?S < 0 ? ?S = 0 ? ?S > 0 ? not enough information

Step 1

0 L of pure CO₂ gas at constant pressure will increase the entropy of the system. This is because the addition of more gas molecules will increase the disorder or randomness of the system, leading to an increase in entropy. Show more…

00:01 Students, let me explain to the question.

00:03 So here they have given the, in the first column, they have given the system.

00:09 And in the second column, they have given the change.

00:13 In the second column, they have given the change.

00:16 We have to decide whether the change described in the second column will increase with the entropy of the system.

00:26 So the change, so whether the change will increase with the...

00:33 Change will increase with the entropy or not with the entropy or not so here the entropy decrease or leave or it is unchanged if you don't have enough information to decide check the not enough information button in the lost column this is the question so in the first system what is the they have given a few moles of carbon dioxide gas.

01:09 Few moles of carbon dioxide gas.

01:11 That is the system in the first column.

01:15 So what is the change here? the change here, carbon dioxide is heated from minus 3 degrees centigrade to 48 degrees centigrade and it is also compressed from a volume of 15 liters to a volume of 5 liters.

01:32 So this is the thing happened.

01:34 So now we have to tell the entropy change.

01:39 So here, by heating the gas, what happens? here, the 3 degrees minus 3, we are increasing to 48 degrees.

01:49 So that means heating...
