The given question is incomplete. But the complete question is this:
A mixture of and is passed over a nickel catalyst at 1000 K. The emerging gas is collected in a 5.00-L flask and is found to contain 8.62 g of CO, 2.60 g of , 43.0 g of , and 48.4 g of . Assuming that equilibrium has been reached, calculate for the reaction.
Explanation:
As the given reaction is as follows.
And, we know that
No. of moles =
Therefore, calculate the moles as follows.
Moles of =
= 2.6808 mol
Moles of =
= 2.6866 mol
Moles of CO =
= 0.307747 mol
Moles of =
= 1.2897 mol
As, we know that
Concentration =
Given volume = 5 L
Hence, calculate the concentration of given species as follows.
Conc. of
= 0.5361
Conc. of
= 0.5373
Conc. of CO =
= 0.06155
and, Conc. of
= 0.2579
Now, expression for equilibrium constant for the given reaction is as follows.
Now, putting the given values into the above formula as follows.
Also, we know that
Consider the equation
Calculate change in moles of gas as follows.
change in gas moles (dn) = 1 + 3 - 1 - 1
dn = 2
As,
It is given that,
T = 1000 K
, R = 0.0821
So,
= 24.70
Thus, we can conclude that value of for the reaction is 24.70.
