Liquid molecules forming a gas and gas molecule forming a liquid are equal in number.
Answer:
0.26 moles........................
The van't Hoff factor is the ratio between the amount of particles produced when a substance is dissolved and the amount of substance being dissolved. If ionization is 0 percent then it would mean that the substance do not dissociate into particles so the van't Hoff factor would be 1. However, when the percent ionization is 100%, then it fully dissociates into ions. For H2SO4 at 100% ionization, the vant hoff factor should be three, two hydrogen ions and one sulfate ion.
Answer: Work was 15 Joules
Explanation: Work W = force F · distance s
W = 5 N · 3 m
Answer:
The partial pressure in mm Hg for each of the species are:
PCO = 0
PH2 = 3874
PCH3OH = 347
The total pressure is 4221
Explanation:
We have to use Ideal gas equation PV = nRT and Partial pressure rule Total Pressure= ∑ Partial pressures.
We have following data:
T= 357K (85+272); nCO=0.078 (2.2/28); nH2 = 2.43 (4.86/2); R=62.36
With equation CO(g) + 2 H2(g) → CH3OH(g) we can calculate the amount of moles the reaction has finished. The limit reagent is CO because is consumed completely and moles CO in flask are 0. According to equation, every CO mol produces one CH3OH mol. That means 0.078 CO moles produces 0.078 CH3OH moles. From Ideal gas equation we have P=nRT/V.
Applying:
PH2=0.87*62.36*357/5=3874
PCH3OH =0.078*62.36*357/5=347
Total P = 3874+347=4221
I hope my answer helps you
