Question
The value of Kc
A. increases B. decreases C. remains the same
The value of Qc
A. is greater than Kc B. is equal to Kc C. is less than Kc
The reaction must:
A. run in the forward direction to restablish equilibrium B. run in the reverse direction to restablish equilibrium. C Remain the same. Already at equilibrium
The concentration of H2 will:
A. increase B. decrease C remain the same
The value of Kc
A. increases B. decreases C. remains the same
The value of Qc
A. is greater than Kc B. is equal to Kc C. is less than Kc
The reaction must:
A. run in the forward direction to restablish equilibrium B. run in the reverse direction to restablish equilibrium. C Remain the same. Already at equilibrium
The concentration of H2 will:
A. increase B. decrease C remain the same
Explanation / Answer
* Equilibrium constant is temperature dependant. And the given equation is endothermic in nature.
According to Le - Chatlier's principle, Increase in temperature will shift the equilibrium towards endothermic reaction. So, amount of reactant will decrease and products will increase.
And thus Kc value increases and Qc > Kc
** The reaction must be run in forward direction to reestablish equilibrium.
The concentration of H2 will increase.
