What happens when the concentration of water inside a cell is lower than the concentration of water outside the cell?
adell [148]

Answer:

Water outside the cell will flow inwards by osmosis to attain equilibrium

Explanation:

In the hypotonic environment, the concentration of water is greater outside the cell and the concentration of solute is higher inside. A solution outside of a cell has a lower concentration of solutes relative to the cytosol.

If concentrations of dissolved solutes are greater inside the cell, the concentration of water inside the cell is correspondingly lower. As a result, water outside the cell will flow inwards by osmosis to attain equilibrium.

Osmosis is a process by which molecules of a solvent tend to pass from a less concentrated solution into a more concentrated one through a semipermeable membrane.

Consider the following reversible reaction. What is the equilibrium constant expression for the given system?
ladessa [460]
The question is incomplete. Complete question is attached below
..........................................................................................................................

Answer: 
Equilibrium constant (K) is defined as the ratio of concentration of product to concentration of reactant.

For the reaction:  2H2O(g)    ↔     2H2(g)      +       O2(g)

Equlibrium constant = \frac{[H_2]^2[O_2]}{[H_20]^2}

[ ] bracket in above expression indicates concentration.
