Methanol, CH3OH, a volatile liquid, is a simple alcohol known as wood alcohol. Methanol has a normal boiling point of 64.60°C and has a heat of vaporization of 35.20 kJ/mol.  What is the vapor pressure (in torr) at 26.25°C?    NOTE: 1 atm = 760 torr

A 3.50 L flask initially contains 0.455 moles of Cl2 and 0.658 moles of H2O.  When the contents of the flask reach equilibrium, O2 is present in a concentration of 0.0279 M.  What is the equilibrium constant, Kc, for this reaction? 2 Cl2(g) + 2 H2O(g)  ⇌ 4 HCl(g) + O2(g)

Information from this problem will be used to answer questions 21 and 22.   Consider the following reaction:  N2 (g)  + O2 (g)  ⇌   2 NO (g) ; Kc = 0.10 If a reaction mixture initially contains 0.350 M N2 and 0.350 M O2, what is the molar concentration of N2 at equilibrium?
