Answer:
THE EQUILIBRIUM CONSTANT EXPRESSION Kc = ![\frac{[C2H5OH]}{[C2H5OC2H5]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OH%5D%7D%7B%5BC2H5OC2H5%5D%7D)
Explanation:
The equilibrium constant, Kc is an expression given by the ratio of the concentrations of the products over the reactants. TN.B: the activities of pure solids and liquids are equal to 1.
Kc =
where n= no of moles
Reaction equation:
2C2H5OH
→ C2H5OC2H5
⇒ Kc =
but [H20] = 1
∴ Kc = ![\frac{[C2H5OH]}{[C2H5OC2H5]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OH%5D%7D%7B%5BC2H5OC2H5%5D%7D)
There are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
