Chapter 18, Problem 1SAQ

Interpretation Introduction

Introduction: A gas has greater entropy than a solid because in a gaseous state, the molecules are free to move in any direction while in solid state, the movement of molecules are restricted.

Expert Solution & Answer

Answer to Problem 1SAQ

Solution:

The reaction given in option (a) will have a positive ΔSsys.

Explanation of Solution

The phase transition is from solid to gas during the chemical reaction, so entropy increases and ΔSsys will be positive.The number of moles of gas decrease during a chemical reaction; 12 mol of gas have decreased to 6 moles, so the entropy decreases and ΔSsys will be negative.

The number of moles of gas decrease during a chemical reaction; 2 mol of gas have decreased to 1 mol, so the entropy decreases and ΔSsys will be negative.

The number of moles of gas decrease during a chemical reaction; 3 mol of gas have decreased to 1 mol, so the entropy decreases and ΔSsys will be negative

Conclusion

Thus, the reaction given in option (a) will have a positive ΔSsys and the correct answer is option (a).
