Questions in this quiz (5)
1What is the correct definition of dynamic equilibrium?
- AThe forward reaction and backward reaction proceed at the same rate. The concentration of the reactants and products are the same.
- BThe forward reaction and backward reaction proceed at the same rate. The concentration of the reactants and products remains constant.
- CThe forward reaction and backward reaction proceed at an increased rate. The concentration of the reactants and products remains constant.
2If the equilibrium expression is [A][B]2 / [C][D]3 (the number 2 and 3 are powers)... what would the equation be?
- AA + 2B < > C + 3D
- BA + 2B < > 3C + D
- C2A + B < > 3C + D
3If 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?
- Amoldm-3
- Bmol-1dm3
- CNo unit
4What is Kc?
- ARate constant
- BEquilibrium constant
- CReversible reaction constant
5A 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)- ACl2 = 0.4 moles
NOCl = 1.7 moles - BCl2 = 0.8 moles
NOCl = 1.7 moles - CCl2 = 0.4 moles
NOCl = 0.9 moles
- ACl2 = 0.4 moles
