What halogen can react with sodium chloride solution to produce chlorine?

ozzi

Answer:

As electro-negativity decreases from Florine to downwards in the group and only Florine is above Chlorine, so Florine should react with sodium chloride solution to produce chlorine.

Consider the hypothetical reaction A(g)←→2B(g). A flask is charged with 0.77 atm of pure A, after which it is allowed to reach e

ankoles [38]

Answer:

For A: The total pressure in the flask at equilibrium is 1.19 atm

For B: The value of $K_p$ for the given equation is 2.016

Explanation:

We are given:

Initial partial pressure of A = 0.77 atm

Equilibrium partial pressure of A = 0.35 atm

For A:

For the given chemical equation:

$A(g)\rightleftharpoons 2B(g)$

Initial: 0.77

At eqllm: 0.77-x 2x

Evaluating the value of 'x'

$\Rightarrow (0.77-x)=0.35\\\\x=0.42$

Equilibrium partial pressure of B = 2x = (2 × 0.42) = 0.84 atm

Total pressure in the flask at equilibrium = $p^A_{eq}+p^b_{eq}=[0.35+0.84]atm=1.19atm$

Hence, the total pressure in the flask at equilibrium is 1.19 atm

For B:

The expression of $K_p$ for given equation follows:

$K_p=\frac{(p_B)^2}{p_A}$

Putting values in above expression, we get:

$K_p=\frac{(0.84)^2}{0.35}\\\\K_p=2.016$

Hence, the value of $K_p$ for the given equation is 2.016
