Let MM(x) be the molar mass of x.
MM(Pb) : MM(PbO)
=207.21 : 223.20 = 451.4 g : x g
cross multiply and solve for x
x=223.2/207.21*451.4
= 486.23 g
Percentage yield = 365.0/486.23= 0.75067 = 75.07% (rounded to 4 sign. fig.)

<u>Answer:</u> The value of
is 0.136 and is reactant favored.
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as ![K_{c}](https://tex.z-dn.net/?f=K_%7Bc%7D)
For the chemical reaction between carbon monoxide and hydrogen follows the equation:
![N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)](https://tex.z-dn.net/?f=N_2%28g%29%2B3H_2%28g%29%5Crightleftharpoons%202NH_3%28g%29)
The expression for the
is given as:
![K_{c}=\frac{[NH_3]^2}{[N_2][H_2]^3}](https://tex.z-dn.net/?f=K_%7Bc%7D%3D%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D)
We are given:
![[NH_3]=0.25M](https://tex.z-dn.net/?f=%5BNH_3%5D%3D0.25M)
![[H_2]=0.75M](https://tex.z-dn.net/?f=%5BH_2%5D%3D0.75M)
![[N_2]=1.1M](https://tex.z-dn.net/?f=%5BN_2%5D%3D1.1M)
Putting values in above equation, we get:
![K_c=\frac{(0.25)^2}{1.1\times (0.75)^3}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%280.25%29%5E2%7D%7B1.1%5Ctimes%20%280.75%29%5E3%7D)
![K_c=0.135](https://tex.z-dn.net/?f=K_c%3D0.135)
There are 3 conditions:
- When
; the reaction is product favored. - When
; the reaction is reactant favored. - When
; the reaction is in equilibrium.
For the given reaction, the value of
is less than 1. Thus, the reaction is reactant favored.
Hence, the value of
is 0.136 and is reactant favored.
