-87.9 kJ, and Kc
Consider the following system at equilibrium where AH
500 K:
=
The value of Qc
Ois greater than K
O is equal to Ke
O is less than Ke
=
PC13 (g) + Cl₂ (g) ⇒ PC15 (9)
When 0.36 moles of PC15 (9) are added to the equilibrium system at constant temperature:
The value of Kc
Oincreases
decreases
O remains the same
The reaction must
Orun in the forward direction to reestablish equilibrium
run in the reverse direction to reestablish equilibrium
O remain in the current position, since it is already at equilibrium
The concentration of PC13 will
O increase
decrease
O remain the same
83.3, at
Previou
