(a)
To determine: The box that represents a system at equilibrium if K c = 1 .
Solution: The given box 1 represents the system at equilibrium.
Explanation:
Given
The balanced chemical reaction is,
A 2 ( g ) + B 2 ( g ) → 2 AB ( 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
Solution: The given box 1 represents the system at equilibrium.
Explanation:
Given
The balanced
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
Since, the box 1 contains equal number of atoms of
Conclusion:
The box 1 represents the system at equilibrium.
