Question

Calculate the value of K p for the equation C ( s ) + CO 2 ( g ) − ⇀ ↽ − 2 CO ( g ) K p = ? given that at a certain temperature C ( s ) + 2 H 2 O ( g ) − ⇀ ↽ − CO 2 ( g ) + 2 H 2 ( g ) K p 1 = 3.13 a t m H 2 ( g ) + CO 2 ( g ) − ⇀ ↽ − H 2 O ( g ) + CO ( g ) K p 2 = 0.699

Answer 1

Kp = 1.53 atm.

Step-by-step explanation:

Hello,

In this case, the first reaction remains the same:

`C ( s ) + 2 H_2 O ( g ) \rightleftharpoons CO_2 ( g ) + 2 H_2 ( g ) ; Kp_1=3.13 atm`

Whereas the second one is doubled:

`2H_2 ( g ) + 2CO_2 ( g ) \rightleftharpoons 2H_2 O ( g ) + 2CO ( g ); Kp_2^2=0.699^2`

In order to, by adding, obtain the main reaction:

`C ( s ) + 2 H_2 O ( g ) +2H_2 ( g ) + 2CO_2 ( g )\rightleftharpoons CO_2 ( g ) + 2 H_2 ( g ) +2H_2 O ( g ) + 2CO ( g )`

Whose combination provides the required value of Kp:

`Kp=Kp_1*Kp_2^2=3.13atm*0.699^2=1.53atm`

Best regards.
