What is the unit of first order reaction?
A zero-order reaction is a reaction that proceeds at a rate that is independent of reactant concentration. Typically with increasing or decreasing reactants
What is the difference between an first order reaction and second order reaction?
rate = k[A], k= rate constant / of proprotion , [] =concentration. (@ = change in []concentration ,@t change in time)a A +bB-> cC from this the rate = -1/a(@[A]/@t) =-1/b(@[B]/@t) =1/c(@[C]/@t where the small letters are the coefficents . so the rate of a reaction is equal to each other when ajusted by the coeffiects . note that the reactants are negative becasue it is decreasing as products form..the basic difference of a fist order and a second is proportions.. fist is directly proportional id est concentration goes up by 2 the rate goes up by two.while second is proportional to the square.concentration goes up by two the rate goes up by 41. First-Order ReactionsA first order reaction (order = 1) has a rate proportional to the concentration of one of the reactants. A common example of a first-order reaction is the phenomenon of radioactive decay. The rate law is:rate = k[A] (or B instead of A), with k having the units of sec-12. Second-Order ReactionsA second-order reaction (order = 2) has a rate proportional to the concentration of the square of a single reactant or the product of the concentration of two reactants:rate = k[A]2 (or substitute B for A or k multiplied by the concentration of A times the concentration of B), with the units of the rate constant M-1sec-1
What are the units for planks constant?
Planck's Constant units are energy-seconds. Planck's Constant is the product of two fundamental Quantum constants, W and C. W is the magnetic charge of "free space" and C is the electric charge of "free space". The value of W= 500 atto Webers and C= 4/3 atto Coulombs. The "free space" impedance z is the ratio of the two quantum constants z=W/C = 375 Ohms.
What is the importance of your choice of units in expressing the value of the ideal gas law constant?
If any other units are used, the value will be different. --Depending on the units you chose the value of the constant differs
What is the gas constant in US units for carbon dioxide?
1,130 Imperial Units (ft lb/slug oR)
What are the units of the diffusion constant?
The units of the diffusion constant are square meters per second (m2/s).
What are the units for the rate constant (kc) in a chemical reaction?
The units for the rate constant (k) in a chemical reaction depend on the overall order of the reaction. For a first-order reaction, the units are 1/time (usually s-1). For a second-order reaction, the units are 1/(concentration time) (usually M-1 s-1).
What are the units of measurement for the rate constant in a chemical reaction?
The units of measurement for the rate constant in a chemical reaction depend on the overall order of the reaction. For a first-order reaction, the units are 1/time (usually s-1). For a second-order reaction, the units are 1/(concentration x time) (usually M-1 s-1).
What are the units of the following if concentrations are expressed in mole per liter?
The units for the following equations would be: Rate of reaction: moles per liter per second Rate constant: per second Reaction order: unitless, but can be expressed as a number Equilibrium constant: unitless, as the units cancel out in the equilibrium expression
What are the units of the catalytic efficiency constant, kcat, in enzyme kinetics?
The units of the catalytic efficiency constant, kcat, in enzyme kinetics are per second (s-1).
What if the value of planck's constant is increased to 1?
The value of Planck's constant depends on the system of units that are being used. The SI units are designed mainly for everyday measurements, where energies are usually of the order of kilojoules and a small period of time is a minute or second. However, the Planck's constant applies events at a subatomic scale so that these "normal" measurement units are not inappropriate.So the question changes in which units would the Plank's constant become 1. Further, the answer depends on how that change is achieved.
What is the unit of first order reaction?
A zero-order reaction is a reaction that proceeds at a rate that is independent of reactant concentration. Typically with increasing or decreasing reactants
What are the units for the equilibrium constant?
The units for the equilibrium constant are dimensionless, meaning they have no units.
What are the standard units used to measure the rate constant in a chemical reaction, known as kc units?
The standard units used to measure the rate constant in a chemical reaction, known as kc units, are typically expressed in moles per liter per second (mol/L/s).
What are the units of equilibrium constant?
The units of equilibrium constant are dimensionless, meaning they do not have any specific units.
Does the equilibrium constant have units?
No, the equilibrium constant does not have units because it is a ratio of concentrations and the units cancel out.
How do you convert acceleration units to velocity units?
To convert acceleration to velocity, you must integrate.Similarly, to convert velocity to distance, you must integrate a second time. This is why the distance covered by a projectile is a second order quadratic equation.
