Question

10. The molecular art depicts the following reversible reaction at equilibrium: COG) +Cl2(g) COCh(e). What can be inferred about the equilibrium constant, K, for this reaction? 1, A) K<1 B) K 1 C) K>1 D) K=0 11. If cells are placed in a hypertonic solution, A) B) C) water diffuses out of the cells and the cells shrink in a process called hemolysis. water diffuses out of the cells and the cells shrink in a process called crenation. water diffuses into the cells and the cells swell and eventually burst in a process called hemolysis. water diffuses into the cells and the cells swell and eventually burst in a process called crenation. D)

Answer 1

10. The equilibrium constant K = [COCl₂ ] / [CO] [Cl₂]

the concentration at equilibrium can be directly correlated to the number of molecules of each species present in the molecular art. Thus K > 1 as number of COCl₂ (trigonal planar shaped) molecules is much larger than that of CO and Cl₂ (both linear).

11. A hypertonic solution is a solution that has a greater concentration of solutes on the outside of the cell when compared with the inside of the cell. Thus by osmosis water diffuses out of the cell and it shrinks in a process called crenation.
