Question 1
Question
What is the correct definition of dynamic equilibrium?
Answer
-
The forward reaction and backward reaction proceed at the same rate. The concentration of the reactants and products are the same.
-
The forward reaction and backward reaction proceed at the same rate. The concentration of the reactants and products remains constant.
-
The forward reaction and backward reaction proceed at an increased rate. The concentration of the reactants and products remains constant.
Question 2
Question
If the equilibrium expression is [A][B]2 / [C][D]3 (the number 2 and 3 are powers)... what would the equation be?
Answer
-
A + 2B < > C + 3D
-
A + 2B < > 3C + D
-
2A + B < > 3C + D
Question 3
Question
If the powers on the top row of an expression are 2 and 2 and on the bottom row are 1 and 3, what would the unit for Kc be?
Answer
-
moldm-3
-
mol-1dm3
-
No unit
Question 4
Question
What is Kc?
Answer
-
Rate constant
-
Equilibrium constant
-
Reversible reaction constant
Question 5
Question
A 2.50 mol sample of NOCl was heated in a sealed container and equilibrium was established at a given temperature. The equilibrium mixture formed contained 0.80 mol of
NO. What is the amount, in moles, of Cl2 and of NOCl in this equilibrium mixture? The equation is; 2NOCl(g) 2NO(g) + Cl2 (g)
Answer
-
Cl2 = 0.4 moles NOCl = 1.7 moles
-
Cl2 = 0.8 moles NOCl = 1.7 moles
-
Cl2 = 0.4 moles NOCl = 0.9 moles
