Question

How can we rationalize the spontaneous nature of mixing?

a) Entropy tends to increase
b) Enthalpy tends to decrease
c) Temperature remains constant
d) Pressure remains constant

Answer 1

Entropy tends to increase, enthalpy tends to decrease, and temperature remains constant in the spontaneous nature of mixing.

Step-by-step explanation:

The spontaneous nature of mixing can be rationalized by understanding that:

• Entropy tends to increase: Energy always transfers spontaneously from a concentrated state to a dispersed state, resulting in an increase in entropy.
• Enthalpy tends to decrease: The entropy of the system remains constant, as some energy becomes unavailable for work during mixing.
• Temperature remains constant: The entropy of any isolated system not in thermal equilibrium always increases.
