Without consulting Appendix B, arrange each group in order of increasing standard molar entropy (S°). Explain.(b) Ice, water vap
Ilya [14]

water vapor>liquid water> ice is the correct order of increasing standard molar entropy.

Since water has more entropy than ice, melting is encouraged by entropy. However, ice has less energy than water, which means that energy favors freezing. The distinction between liquid water, ice, and water vapor is that each of them is a different state of matter. Ice represents the solid state, liquid water the liquid state, and water vapor the gaseous state of water. As a result, the system's entropy reduces. A vapour condensing is an exothermic process. Consequently, the environment's entropy rises. however, the environment's growth in entropy grows. Since the gas state has a higher entropy than the liquid state does, the entropy change for the vaporization of water is positive.

A gaseous mixture containing 1.5 mol ar and 3.5 mol co2 has a total pressure of 8.6 atm. What is the partial pressure of co2?
Sindrei [870]

Answer:

The partial pressure of CO2 is 6,02 atm

Explanation:

This is the formula por partial pressure

\frac{Gas pressure}{Total pressure} \\ = \frac{Gas moles}{Total moles} \\

Total moles ---> 1,5 + 3,5 = 5 moles

Partial pressure CO2 / 8,6 atm = 3,5 moles CO2 / 5 moles (CO2 + Ar)

Partial pressure CO2 = (3,5 moles CO2 / 5 moles) . 8,6 atm = 6,02 atm
