In preparing a drug design, it is determined that the drug will work better if a molecule of NaCl can be dissociate to free ions in the plasma membrane of a cell. Is this plan feasible? O No, the energy needed to dissociate is too high in the plasma membrane. Yes, because there are special proteins in the plasma membrane that specifically break NaCl into free ions. O No, even though NaCl would freely dissociate the ions would be lost. Yes, because the plasma membrane is an aqueous solution there is no problem.

This chemical equation represents a reaction: 2 ICL (g) L (g) + 3 Cl (g) Suppose a closed flask contains only gaseous ICI,, and the concentration of ICl, is 0.10 M. How will these initial conditions affect the progress of the reaction? The concentration of the reactant will decrease, and the concentrations of the products will increase, until the concentration of each product equals 0.10 M. O The concentrations of the reactant and the products will increase until the concentration of each product equals 0.10 M. The concentration of the reactant will decrease, and the concentrations of the products will increase, until the rate of the forward reaction equais the rate of the reverse reaction. The concentrations of the reactant and the products will increase until the rate of the forward reaction equals the rate of the reverse reaction
