The equilibrium constant, Kp, for the following reaction is 0.497 at 500K.PCl5(g) PCl3(g) + Cl2(g)If an equilibrium mixture of t
Anestetic [448]

<u>Answer:</u> The equilibrium partial pressure of chlorine gas is 0.360 atm

<u>Explanation:</u>

For the given chemical equation:

PCl_5(g)\rightleftharpoons PCl_3(g)+Cl2(g)

The expression of K_p for above reaction follows:

K_p=\frac{p_{Cl_2}\times p_{PCl_3}}{p_{PCl_5}}

We are given:

K_p=0.497\\p_{PCl_3}=0.651atm\\p_{PCl_5}=0.471atm

Putting values in above equation, we get:

0.497=\frac{p_{Cl_2}\times 0.651}{0.471}\\\\p_{Cl_2}=0.360atm

Hence, the equilibrium partial pressure of chlorine gas is 0.360 atm

"Which statement is true about the removal of a terminal phosphate" from ATP? Choose one: A. The reaction is associated with a p
Mamont248 [21]

Answer:

C. The reaction is energetically favorable.

Explanation:

The reaction which shows the removal of the terminal phosphate from the ATP is shown below:

ATP+H_2O\rightarrow ADP+P_i+\ energy

The Gibbs' free energy change of this reaction, \Delta G^0=-7.3\ kcal/mol

Hence, Option A is not correct.

It is a type of hydrolysis reaction in which water is being added to the molecule.

Hence, Option B is not correct.

The Gibbs' free energy change is negative which means that the reaction is energetically favorable.

Option C is correct.
