## Other questions in this quiz

## 2. What is a catabolic pathway in terms of Gibbs energy?

- Change in Gibbs < 0 exergonic pathways eg degradation of nutrients to obtain available energy
- Change in Gibbs > 0 endogonic pathways eg degradation of nutrients to obtain available energy
- Change in Gibbs < 0 exergonic pathways eg biosynthesis
- Change in Gibbs > 0 endogonic pathways eg biosynthesis

## 3. Which of these statements is not related to entropy

- Entropy increases until equilibrium is reached in an isolated system
- Entropy never decreases in an isolated system
- An Isolated system spontaneously passes to the most probable state (a macroscopic state with the highest no. of microscopic state)
- Change in S> change in H / T
- At equlibrium entropy always decreases in an isolated sytsem
- S= Kb ln W
- Inequality of Clausius - (when energy changes form- some part is lost as entropy)

## 4. Why does in liquids the Change in U approximately equals to Change in H when volume pressure work occcurs?

- Because energy in solids is negligible
- Because pressure in solids is negligible
- Because pressure in liquids is negligible
- Because energy in liquids is negligible

## 5. Which of the equations is Boltzmann constant used for?

- For absolute value of Energy
- For absolute value of Entropy
- For absolute value of Enthalpy
