REACTION KINETIC PART 2

What does a differential rate equation primarily show?

• The overall speed of a chemical reaction.

• The relationship between the rate of disappearance of reactants and the formation of products.

• The energy required to initiate a reaction.

• The equilibrium constant of a reversible reaction.

For the reaction N₂(g) + 3H₂(g) → 2NH₃(g), if the disappearance rate of hydrogen is 0.30 Ms⁻¹, what is the formation rate of NH₃?

• 0.10 Ms⁻¹

• 0.20 Ms⁻¹

• 0.30 Ms⁻¹

• 0.90 Ms⁻¹

Which statement accurately describes reaction order?

• It can be determined directly from the stoichiometric coefficients of a balanced equation.

• It shows how the rate of a reaction is affected by reactant concentration.

• It is always equal to the number of moles of the reactant in the balanced equation.

• It is a constant value that does not change with temperature.

What is the definition of half-life in the context of chemical kinetics?

• The total time it takes for a chemical reaction to reach completion.

• The time required for the concentration of a reactant to decrease to half of its initial concentration.

• The point at which the reaction rate is exactly half of its maximum rate.

• The duration for which a chemical reaction remains stable.

What is the half-life equation for a zero-order reaction?

• t1/2 = [A]o / k

• t1/2 = [A]o / 2k

• t1/2 = ln(2) / k

• t1/2 = 1 / (k[A]o)

What is the rate law for a first-order reaction?

• Rate = k

• Rate = k[A]

• Rate = k[A]^2

• Rate = k[A]^0
