Answer:
The equilibrium constant Kp for this reaction is 0.0030
Explanation:
Step 1: Data given
Partial pressure at the equilibrium:
pHCl = 76.9 atm
pO2 = 66.3 atm
pCl2 = 40.7 atm
pH2O = 65.1 atm
Step 2: The balanced equation
4 HCl(g) + O2(g) → 2 Cl2(g) + 2 H2O(g)
Step 3: Calculate the equilibrium constant Kp
Kp = ((pH2O²)*(pCl2²)) /(pO2)*(pHCl^4))
Kp = (65.1²*40.7²) / (66.3*(76.9^4))
Kp = 0.0030
The equilibrium constant Kp for this reaction is 0.0030

Answer B
Given :
The atomic weight of copper is 63.5 gm.
To Find :
The total number of gram atoms and number of atoms present in 100 gram of copper.
Solution :
We know, 1 gram atom is equal to mass of one mole of copper i.e. 63.5 gm.
So, number of gram atom in 100 gram of copper is :
n = 100/63.5
n = 1.57 gram atom
Now, number of atoms on gram atom is :
Therefore, total number of gram atoms and number of atoms present in 100 gram of copper is 1.57 gram atom and .
Hence, this is the required solution.
