Question

Mixing of non-reactive gases is generally accompanied by:

• A. Decrease in entropy
• B. Increase in entropy
• C. Increase in enthalpy
• D. decrease in temperature

Answer 1

The correct option is B Increase in entropy

When the non-reactive gases are mixed. The number of particles and as the number of particles increases, the number of ways of energy distribution increases, randomness increases and thus entropy increases.
