HBrO(aq) + H2O(l) ⇄ H3O+(aq) + BrO−(aq)   Keq=2.8×10−9
Verdich [7]

Answer: The equilibrium concentration of BrO^- will be much smaller than the equilibrium concentration of HBrO, because Keq<<1

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{eq}

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

HBrO(aq)+H_2O(l)\rightarrow H_3O^+(aq)+BrO^-(aq)

The expression for K_{eq} is written as:

K=\frac{[H_3O^+]\times [BrO^-]}{[HBrO]}

Concentration of pure solids and liquids is taken as 1.

K=2.8\times 10^{-9}

Thus as K_{eq} , That means the concentration of products is less as the reaction does not proceed much towards the forward direction.

Bose-Einstein condensation occurs at what temperature?
lyudmila [28]

Bose Einstein condensation occur at temperature very close to absolute zero i.e 273.15 degrees centigrade.. Under such conditions, large quantity of Boson occupies the lowest quantum state, at which point microscopic quantum phenomena becomes apparent macroscopically.  A BEC is formed by cooling a gas of extremely low density about one hundred thousandth the density of normal air, to ultra low temperature.
