Question

I don't know what to do

A certain substance, X, has a triple point temperature and pressure of 20degreeC and 2.0 atm and a critical point temperature and pressure of 210degreeC and 150 atm. The equilibrium line between solid and liquid phase has a positive slope. Which one of the following statements can not be true? At a pressure of O2 of 1.00 atm, the mole fraction of dissolved O2 in water is 1.6 times 10-5 at 333 K. What pressure of O2 would be required to have a solution of 2.0 times 10-3 g O2 in 200 g H2O at 333 K? MM O2 = 32.08 g/mol. Calculate deltaG for the following reaction at 400 K at pressures of NH3(g) and CO2(g) of 1.00 atm and 3.00 atm, respectively. NH4CO2NH2(s) rightarrow 2NH3(g) + CO2(g) deltG0 = 27.6 kJ

Explanation / Answer

Question 37 C. X can exist as a gas at 25
