Question

Part A 

Does the entropy of the system increase, decrease, or stay the same for each of the following conditions. 

Drag the appropriate items to their respective bins. 

• The volume of a gas increases. Increases.

• Equal volumes of ethanol and water are mixed to form a solution. 

• The temperature of the system increases. 

increases	Decrease	Stays the same

Problem 19.46-Enhanced with Feedback 

Complete the following statements that compare these two constitutional isomers. 

Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer.

 1. At 25° C cyclopropane is a and propylene is a which means that lattice effects

 2. Comparing the structure of the two compounds indicates that the isomer with greater free rotation is are important liquid gas propylene

 3. Given the analysis of lattice effects and structure, the isomer with a higher standard molar entropy at 2 is

Answer 1

1) If the volume of gas increases then the entropy of the system increases.

   If equal volume of ethanol and water are mixed to form a solution then the entropy of the system increases.

   If the temperature of the system increases then the entropy of the system increases.

2)   At 25 degree centigrade cyclopropane is a gas and propylene is a gas,which means that lattice effects are not important.

    comparing the structure of the two compounds indicates that the isomer with greater free rotation is propylene.

the isomer with a higher standard molar entropy at 25 degree is propylene.

Answer 2

2. Comparing the structure of the two compunfs indicates that the isomer with greater free rotation is propylene.
3. Given the analysis of lattice effects an dstructure, the isomer with a higher standard molar entropy at 25° C is propylene.
