Phosphorous trichloride and phosphorous pentachloride equilibrate in the presence of molecular chlorine according to the reaction: pcl3 (g) + cl2 (g) → pcl5 (g) an equilibrium mixture at 450 k contains ppcl3 = 0.348 atm, pcl2 = 0.441 atm, and ppcl5 = 10.24 atm. what is the value of kp at this temperature? phosphorous trichloride and phosphorous pentachloride equilibrate in the presence of molecular chlorine according to the reaction: (g) + (g) (g) an equilibrium mixture at 450 k contains = 0.348 atm, = 0.441 atm, and = 10.24 atm. what is the value of kp at this temperature? 66.7 1.50 ⋅ 10−2 12.99 1.57 9.45

Answer : The value of at this temperature is 66.7

Explanation : Given,

Pressure of at equilibrium = 0.348 atm

Pressure of at equilibrium = 0.441 atm

Pressure of at equilibrium = 10.24 atm

The balanced equilibrium reaction is,

The expression of equilibrium constant for the reaction will be:

Now put all the values in this expression, we get :

Therefore, the value of at this temperature is 66.7

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

it is the most commonly accepted one
