Question
Name: Date: Section: Prelaboratory Assignment: Spectrophotometric Determination of an Equilibrium Constant. 1. At 227°C, carbon monoxide gas reacts with hydrogen gas to form one mole of methanol, CH,OH. At equilibrium, the partial pressures of the gases are Pco= 0.295 atm, PH2 1.25 atm, and PCH3OH = 2.18 atm. a) Write a balanced equation for the reaction b) Calculate the equilibrium constant for the reaction. 2. Consider the reaction: A+B=C+ 3D A solution was prepared by mixing 50.00 mL of 1.00 x 10³ M A, 100 mL of 2.00 x 10 MB, 10.0 mL of 1.0 M C and 75 mL of 1.50 x 10³M D. At equilibrium, the concentration of D was measured to be 6.0 x 10 M. a) Calculate the equilibrium concentrations of each species b) Calculate the equilibrium constant. 3. Consider the reaction: # 2NO2(g) + Cl2(g) 2NOCI The initial pressure of NO, was 1.577 atm and the initial pressure of Cl₂ was 0.427 atm. At equilibrium, the partial pressure of NOCI is 0.624 atm. Calculate K.
