4 minutes rate of reaction challenge

What is the definition of rate law in a chemical reaction?

• An equation that relates the rate of a reaction to the concentrations of reactants

• The speed at which a reaction occurs

• A formula to calculate the energy change in a reaction

• The amount of product formed in a reaction

In a rate law, what does the order of reaction with respect to a particular reactant indicate?

• It indicates how the rate of the reaction changes with changes in the concentration of that reactant.

• It shows the molecular weight of the reactant

• It indicates the physical state of the reactant

• It represents the color change during the reaction

If the rate constant of a reaction is 0.05 s^-1, what is the order of the reaction?

• Zero order

• First order

• Second order

• Third order

For a reaction with the rate law, rate = k[A]²[B], what is the order of reaction with respect to A and B?

• 3 for A, 1 for B

• 2 for A, 3 for B

• 2 for A, 1 for B

• 1 for A, 2 for B

What happens to the rate of a reaction if the concentration of a reactant is doubled in a first-order reaction?

• The rate of the reaction remains the same.

• The rate of the reaction triples.

• The rate of the reaction decreases.

• The rate of the reaction doubles.

In a rate law, what does the overall order of reaction represent?

• Sum of individual orders of all reactants

• Equilibrium constant

• Activation energy

• Average rate of reaction

If the rate constant of a reaction is 0.1 M^-1 s^-1, what is the order of the reaction?

• Zero order

• First order

• Second order

• Third order

For a reaction with the rate law, rate = k[A][B]², what is the overall order of reaction?

• 1 with respect to A, 2 with respect to B

• First order

• Third Order

• 2 with respect to A, 1 with respect to B
