4.The minimal value of entropy is zero.

Homework Answers

Answer #1

All the statements given above for entropy are correct and justifiable.

1. Entropy is a measure of disorder in a system.

TRUE, it tells us about randomness in a system

2. Entropy is a state function.

TRUE, entropy doesnt depends on the path followed for process instead only depends on the initial and final states of system.

3. An increase in entropy is associated with an increase in the order of a system.

FALSE, it is associated with disorder or chaos in the system so when the entropy increases the disorderness of system increases

4.The minimal value of entropy is zero

TRUE, the value of entropy at absolute zero temperature(-273.15 0c) is accounted to be zero and is minimal value.

Which of the following statements about spontaneity are true? A decrease in the entropy of the reaction ensures that only reactants will be formed during the course of a reaction. A reaction with an increase in enthalpy and entropy will be spontaneous at all temperatures. A reaction with a negative value for ΔGnonstand will result in only products being present at the end of the reaction. The enthalpy change in a reaction can be used to predict if a reaction...
