At 400 k, the equilibrium for the isomerization reaction a b is rapidly established. at 2.5 atm, respectively. this temperature, the vapor pressures of a and b are 2 atm and gaseous a and b are placed in a cylinder fitted with a piston and maintained at 400 k. the cylinder is filled at i atm and movement of the piston slowly decreases the volume of the reacting system. at a pressure of 2.2 atm, a dew point is observed. assuming ideal-liquid solutions, calculate the following: (a) equilibrium constant for the reaction a (g) (b) equilibrium constant for the reaction a (1)艹b (1). he house at 75 e is compressed adiabatically

Which of the following pressures is equal to 760 mm hg? 2.0 atm 101.3 pa 101,300 kpa 101,300 pa

If 34.2 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 299 kelvin and 1.21 atmospheres? 2 li (s) + 2 h2o (l) yields 2 lioh (aq) + h2 (g)

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
