Phosgene, COC12, is the chemical warfare gas commonly called mustard gas. It decomposes as 3) written below. At 900 C, the Kç = 0.83. Assume 0.400 mol of COCl2 are admitted into a 2.00 L container at 900C. What will be the equilibrium concentrations of CO, Cl2 and COCI2? USE THE QUADRATIC for this one. You will NOT need to use quadratic on a test but for take home problems it is OK. COC2 <=-=> CÓ + Ch [CO]eq = (Clh]eq * [COCL]eq =.

. Many sugars undergo a process called mutarotation, in which the sugar molecules interconvert between two isomeric forms, finally reaching an equilibrium between them. This is true for the simple sugar glucose, C6H12O6, which exists in solution in isomeric forms called alpha-glucose and beta-glucose. If a solution of glucose at a certain temperature is analyzed, and it is found that the concentration of alpha-glucose is twice the concentration of beta-glucose, what is the value of K for the inter-conversion reaction?
