question 37

Multiple Choice

Consider the following reaction at a certain temperature:
PCl₅(g)
$f$
PCl₃(g) + Cl₂(g)
K_c = 0.100
At equilibrium,[PCl₅] = 2.00 M and [PCl₃] = [Cl₂] = 1.00 M.If suddenly 1.00 M PCl₅(g) ,PCl₃(g) ,And Cl₂(g) Is added,What is the equilibrium concentration of Cl₂(g) ?

• A) 3.0 M
• B) essentially zero
• C) 0.65 M
• D) 2.75 M
• E) 3.35 M
