An aqueous solution of nitrous acid (HNO2) has a ?G= 19.1 kJ. What is the pH when [NO2-]=1.00 M, [HNO2]=1.00 M, and the ?G=0?
Use the van der Waals equation of state to plot the compressibility factor, Z, against P for methane at 180K and 250K. Hint: calculate Z as a function of V/n and P as a function of V/n, and then plot Z Vs. P.
