1. What is the equilibrium constant (K) for a reaction at equilibrium?

The ratio of concentrations of products to reactants · The sum of concentrations of all species · The difference in concentrations of products and reactants · The rate of the forward reaction

2. Which of the following changes does NOT affect the equilibrium position?

Change in temperature · Change in pressure · Addition of inert gas · Change in concentration of reactants

3. For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g), what happens when pressure is increased?

Equilibrium shifts to the left · Equilibrium shifts to the right · No effect on equilibrium · Reaction stops completely

4. Which of the following statements is true about dynamic equilibrium?

The concentrations of reactants and products are equal · The rate of forward reaction equals the rate of reverse reaction · The reaction has completely stopped · Only reactants are present

5. What effect does increasing temperature have on an exothermic reaction at equilibrium?

Shifts equilibrium to the right · Shifts equilibrium to the left · No effect on equilibrium · Increases the rate of the reaction
