Consider the following reaction:                                   Xe(g)  + 2 F2(g) →  XeF4(g)   A reaction mixture initially contains 2.24 atm Xe and 4.27 atm F2.  If the equilibrium pressure of Xe is 0.34 atm, find the equilibrium constant (Kp) for the reaction.  

Express the equilibrium constant for the following reaction.                   2 CH3Cl(g) + Cl2 (g) ⇔  2 CH2Cl2  (g) +  H2 (g)

A mixture of the following proteins was added to a positively charged ion exchange chromatography column at pH 7.  After adding the proteins, the column was rinsed with a gradually increasing concentration of NaCl until all proteins were removed. Given the isoelectric points (pI) values below, what is the order of removal (elution) of proteins, from first to last?    Ribonuclease (pI = 9.0) Aconitase (pI = 7.0) Hemoglobin (pI = 6.0) Albumin (pI = 4.1)
