B.) [NOBr]2/[NO2][Br]2
C.) [NO2][Br]2/[NOBr2]
D.) [NOBr]2/[NO]2[Br2]
Explanation:
D mole is a power. .......
[NOBr]2/[NO]2[Br2] is the equilibrium expression for 2NO+Br2⇌2NOBr. Therefore, the correct option is option D.
What is equilibrium?When the observable qualities, such as colour, pressure, temperature, concentration, etc. do not vary, the process is said to be in equilibrium. As "balance" is the definition of the word "equilibrium," it follows because a chemical reaction reflects a balance among the substances and outcomes involved in the reaction.
In some physical processes, such as the melting of ice at 0°C, where both the two substances are present at equilibrium, the equilibrium state can also be observed. Physical equilibrium refers to the equilibrium that results from physical processes like the melting of solids. [NOBr]2/[NO]2[Br2] is the equilibrium expression for 2NO+Br2⇌2NOBr.
Therefore, the correct option is option D.

The correct equilibrium constant expression for the given chemical reaction is Keq = [Cu²⁺] / [Ag⁺]².
What is equilibrium constant?Equilibrium constant of any reaction at the equilibrium state will be define as the ratio of the concentration of products to the concentration of the reactants.
Given chemical reaction is:
Cu(s) + 2Ag⁺(aq) ⇄ Cu²⁺(aq) + 2Ag(s)
Equilibrium constant for the above reaction will be written as:
Keq = [Cu²⁺][Ag]² / [Cu][Ag⁺]²
But in the above reaction at the product side silver is present in pure solid form and at the reactant side copper is present in pure solid form and concentration of these elements equals to one in equilibrium state, so that equation becomes:
Keq = [Cu²⁺] / [Ag⁺]²

b)R equals 0
c)number of moles and temperature are constant
d)number of moles and pressure are constant
The ideal gas law is equivalent to Charles's law when number of moles and pressure are constant (option D)
Ideal gas equationPV = nRT
Where
P is the pressure V is the volume n is the number of mole R is the gas constant T is the temperature Charles' lawCharles' law states as follow:
V₁ / T₁ = V₂ / T₂
Where
V₁ is the initial volume T₁ is the initial temperature V₂ is the new volume T₂ is the new temperature How to relate ideal gas equation to Charles' lawPV = nRT
Divide both side by T
PV / T = nR
Divide both side by P
