(a)
To determine: The box that represents a system at equilibrium if Kc=1 .
Solution: The given box 1 represents the system at equilibrium.
Explanation:
Given
The balanced chemical reaction is,
A2(g)+B2(g)→2AB(g)
The system at equilibrium means the rate of the forward reaction is equal to the rate of the backward reaction. The system which contains the equal number of atoms of A , B and AB will be considered at equilibrium.
Since, the box 1 contains equal number of atoms of A , B and AB . Therefore, this box represents the system is at equilibrium.
Conclusion:
The box 1 represents the system at equilibrium.
To determine: The box that represents a system at equilibrium if Kc=1 .
Solution: The given box 1 represents the system at equilibrium.
Explanation:
Given
The balanced
- A2(g)+B2(g)→2AB(g)
The system at equilibrium means the rate of the forward reaction is equal to the rate of the backward reaction. The system which contains the equal number of atoms of A , B and AB will be considered at equilibrium.
Since, the box 1 contains equal number of atoms of A , B and AB . Therefore, this box represents the system is at equilibrium.
Conclusion:
The box 1 represents the system at equilibrium.
(b)
To determine: The box that represents the system at Q<Kc if Kc=1 .
(c)
To determine: The correct increasing magnitude of ΔG order of the boxes for the given reaction.
