Can equilibrium constants be negative?
No. An equilibrium constant is derived from the products, powers, and ratios of the activities (essentially the concentrations) of the species that are in equilibrium. Since there is no such thing as a negative concentration, there is no way their products, powers or ratios can yield a negative number.
Which term refers to the condition that exist when no net change in concentration results from diffusion A. concentration B. equilibrium C. osmosis D. Randomness?
B. Equilibrium - when equal particles continue to move in both directions there is no further net change in the concentration on either side
What is the difference in the concentration of a substance across a space is called concentration?
Concentration Gradient
What is equilibrium conversion how does it effect design of reactor?
equilibrium conversion is that which is at equilibrium concentration
Looking at a free energy diagram for an equilibrium reaction what scenarios will favor the formation of more product?
The concentration of reactants is greater than the concentration of reactants at equilibrium. The concentration of products is less than the concentration of products at equilibrium
Looking at a free energy diagram for an equilibrium reaction which of the following scenarios will favor the formation of more reactant?
The concentration of reactants is less than the concentration of reactants at equilibrium. The concentration of products is greater than the concentration of products at equilibrium.
What happens to the equilibrium potential of sodium as you decrease the extracellular sodium concentration?
The equilibrium potencial of sodium decreases as you decrease its extracellular concentration
What is the difference between an isotonic solution and equilibrium?
equilibrium is reaching that state of equal concentration. isotonic is how you describe the cell that has equal concentration.
What is the continuous movement of particles but no overall change in concentration?
exocytosis
The keq of a reaction is 4 times 10 to the -7th at equilibrium the?
If the K is 410, then at equilibrium the concentration of the product of the products is 410 times the concentration of the products of the reactants. For example, in A + B ==> C + D, if K=410, then CxD will be 410 x more than AxB
What is the eventual result of diffusion describe concentration prior to and at this point?
The eventual result of diffusion is equilibrium. The concentrations prior to this point would be uneven. The solutes then diffuse from areas of high solute concentration to areas of low solute concentration. After diffusion, at equilibrium, the concentration will be even in different areas.
What of the following characterizes reaction at equilibrium?
The reactants concentration is equal to products concentration.
