Homework Answers
1. The first reaction show increase in entropy as solid is converted to solid and gas. As we know gas has more entropy due to more randomness or disorder than liquid than solid.
2. In the second reaction, there is a decrease in entropy as liquid is converted into solid.
3. In the third reaction, the entropy is decreased as 2 different reactants (gases) are combining to form one product(gas). When both are given in gaseous form we have to see for the number of reactants.
4. In the 4th reaction, solid is converted in liquid. Hence there is increase in entropy as liquid as has more entropy than solid.
