Consider a sample that is a mixture composed of biphenyl, benzoic acid, benzyl alcohol. The sample is spotted on a TLC plate and developed in a dichloromethane-cyclohexane solvent mixture. Predict the relative Rf values for the three components in the sample.
For carbon tetrachloride, the boiling point constant is 5.03°C·kg/mol, and the boiling point of pure carbon tetrachloride is 76.50°C.
Consider the following reaction: Xe(g) + 2 F2(g) ? XeF4(g) Kc = 1.58 × 10-8 A reaction mixture initially contains 2.24 atm Xe, 4.27 atm F2, and no XeF4. If the equilibrium pressure of Xe is 0.34 atm, find the equilibrium constant (Kp) for the reac..
