Question

Consider the reaction.

2 upper N upper o upper c l double-headed arrow 2 upper N upper O (g) plus upper C l subscript 2 (g).


At equilibrium, the concentrations are as follows.


[NOCl] = 1.4 ´ 10–2 M

[NO] = 1.2 ´ 10–3 M

[Cl2] = 2.2 ´ 10–3 M


What is the value of Keq for the reaction expressed in scientific notation?

Answer 1

its A

Step-by-step explanation:

Answer 2

Answer: The value of Keq for the reaction expressed in scientific notation is
`1.6* 10^(-5)`

Step-by-step 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.

For the given chemical reaction:

`2NOCl(g)\rightarrow 2NO(g)+Cl_2(g)`

The expression for
`K_(eq)` is written as:

`K_(eq)=([NO]^2* [Cl_2])/([NOCl]^2)`

`K_(eq)=((1.2* 10^(-3))^2* (2.2* 10^(-3)))/((1.4* 10^(-2))^2)`

`K_(eq)=1.6* 10^(-5)`

The value of Keq for the reaction expressed in scientific notation is
`1.6* 10^(-5)`
