What are the units of k for each reaction order?
The units of the rate constant, k, depend on the overall reaction order. The units of k for a zero-order reaction are M/s, the units of k for a first-order reaction are 1/s, and the units of k for a second-order reaction are 1/(M·s).
What is 4th order subwoofer?
A fourth order enclosure (vented box) is a sealed enclosure with the additon of a port tuned to a specific frequency. The port extends the low frequency response of the basic sealed enclosure usually providing a lower cut-off frequency.
What are the units for the rate constant of a third order reaction?
If the reaction is third order, the rate constant should have units of L2 mol-2 s-1.
What are the units of k in a fourth order reaction?
Therefore, the unit of k is (mol/L)−3t−1 for fourth order reaction.
What is the unit of rate constant of second-order reaction?
Solution : `”mol”^(-1)”L s”^(-1)` is the unit of rate constant for second order reaction.
What are the units of a first order rate constant?
Because the units of the reaction rate are always moles per liter per second, the units of a first-order rate constant are reciprocal seconds (s−1).
What is the unit of the rate constant for a reaction of order 3 2?
sec^-1
For a reaction having order equal to 3/2 , the units for rate constant are sec^-1 .
What are the units for rate constant for zero-order & second-order reaction?
The rate constant of the reaction is denoted by k. In a zero-order reaction, the rate constant is expressed as concentration/time or M/s, where ‘M’ is the molarity and ‘s’ is one second. ∴ k = mol L–1 s–1 is the unit of rate constant.
What is the unit of second-order rate constant?
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 is the unit of rate constant of first order reaction?
reciprocal seconds
Because the units of the reaction rate are always moles per liter per second, the units of a first-order rate constant are reciprocal seconds (s−1).
What are the units for rate constant in chemistry?
More generally speaking, the units for the rate constant for a reaction of order (m +n) ( m + n) are mol1−(m+n) L(m+n)−1 s−1. mol 1 − ( m + n) L ( m + n) − 1 s − 1. The table below summarizes the rate constant units for common reaction orders. Note that the units in the table can also be expressed in terms of molarity ( M) instead of mol/L.
What is the resistance of a 4 ohm subwoofer?
In practical terms, if two 4-ohm subwoofers are connected in parallel, the total resistivity would be 4/2, which gives resistance of 2 Ω. With subwoofers in parallel, you get louder sound but suffer lower sound quality.
What is the difference between 2 ω and 4 Ω subwoofers?
Comparison Chart 2 Ω subwoofer 4 Ω subwoofer Louder sound Softer sound Poorer sound quality Better sound quality Generally more expensive Generally cheaper than 2-ohm subwoofers Lower resistivity Higher resistivity
What is the impedance of a subwoofer?
The amplifier is made to work with speakers within a specific impedance range. You’ll notice that most stereo speaker designed for home use come with 8 ohms ratings while vehicle speakers are often 4 or 2 ohms. 2 Ω and 4 Ω units are different in the following areas: Let’s now see what each of these subwoofers is.
