What is the unit of rate constant of second order reaction?
For the units of the reaction rate to be moles per liter per second (M/s), the units of a second-order rate constant must be the inverse (M−1·s−1). Because the units of molarity are expressed as mol/L, the unit of the rate constant can also be written as L(mol·s).
What are the units of rate constant for zero-order reactions?
The unit of the rate constant in a zero-order reaction is given by concentration/time or M/s where ‘M’ is the molarity and ‘s’ refers to one second.
What are the units of the rate constant for this reaction?
The rate constant has units of reciprocal seconds (s−1) because the reaction rate is defined in units of concentration per unit time (M/s).
What are the units for the rate constant of a first-order reaction?
k is the first-order rate constant, which has units of 1/s. The method of determining the order of a reaction is known as the method of initial rates. The overall order of a reaction is the sum of all the exponents of the concentration terms in the rate equation.
What is the unit of third order reaction?
Third-order reaction equation: dA/dt = -kA3….
| Reaction Order | Units of k |
|---|---|
| Second | L/mol/s |
| Third | mol-1 L2 s-1 |
What is the unit of zero order?
The unit of the rate constant in a zero order reaction is given by concentration/time or M/s where ‘M’ is the molarity and ‘s’ refers to one second.
What is the rate of zero order reaction?
The rate law for a zero-order reaction is rate = k, where k is the rate constant. In the case of a zero-order reaction, the rate constant k will have units of concentration/time, such as M/s.
What are the units of rate constant for third order reaction?
Third-order reaction equation: dA/dt = -kA3….Some Facts About Third Order Rate Law.
| Reaction Order | Units of k |

What is the unit of rate constant for third order reaction?
What is meant by zero order reaction?
Definition of zero-order reaction : a chemical reaction in which the rate of reaction is constant and independent of the concentration of the reacting substances — compare order of a reaction.
What are the units of 3rd order and first order rate constant?
