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
