If someone could please be kind enough to see me through this problem?
Calculate the value of Kp for the equation C(s) + CO2(g) <--> 2CO(g) Kp?
Given that at a certain temperature..
C(s) + 2H2O(g) <--> CO2(g) + 2H2(g) Kp1 = 3.03 and
H2(g) + CO2(g) <--> H2O(g) + CO(g) Kp2 = 0.637
i sq rooted the last equation: (0.637)^2 = 0.405769 and then multiplied by 3.03 = 1.2294
is that correct?
I think what you want to do is multiply equation 1 by 2 and add to equation 2. I believe that will give you the equation you want. To find the Kp value, it will be (Kp1)^2*Kp2 = ?
Hi Dr. Bob,
(3.03)^2 * 0.637 = 5.85?
What would I do with the first equation that i got?
OHH (2.567)^2*0.637 = 4.197?!
.. or was that a fail epiphany
If I take the square root of 3.03*0.637 I don't get 4.197.
is this answer correct? these form need to verify is these answers are correct. ty
To calculate the value of Kp for the given equation, you need to use the relationship between Kp values of reactions that can be combined to obtain the desired reaction.
The given reaction is: C(s) + CO2(g) <--> 2CO(g)
First, let's check the stoichiometric coefficients of the species in the given reaction and compare them to the stoichiometric coefficients in the provided equilibrium reactions.
Given equilibrium reactions:
1) C(s) + 2H2O(g) <--> CO2(g) + 2H2(g) (Kp1 = 3.03)
2) H2(g) + CO2(g) <--> H2O(g) + CO(g) (Kp2 = 0.637)
From reaction 1, we can see that the stoichiometric coefficient of CO2 is 1, and in the given reaction, it is also 1. So, you don't need to make any changes to the given equation for CO2.
From reaction 2, we see that the stoichiometric coefficient of CO2 is also 1, but in the given reaction, it is multiplied by 2. Therefore, we need to square the Kp2 value since the reaction is multiplied by its coefficients:
(Kp2)^2 = (0.637)^2
After calculating (Kp2)^2, you can multiply it with Kp1 to obtain Kp for the given reaction:
Kp = (Kp2)^2 * Kp1
Substituting the values:
Kp = (0.637)^2 * 3.03
Calculating this expression gives a value of approximately 0.769.
Therefore, the correct answer to your question is not 1.2294 but rather 0.769.
