The value of k in a rate law?
K is known as the rate coefficient, or the rate constant. The value of k is particular, and varies from reaction to reaction. It is dependent on different factors such as temperature, pressure, concentration, solvent, presence of a catalyst, etc., and therefore a change in any of these gives you a new value for k. To determine the value of k, you must use the experimental data to determine if you have a zeroth order, first order, or second order reaction. As indicated by the equation below, you must also have the actual rate.Rate= k[A]m[B]n[C]pYour overall reaction order is given by the sum of the orders of reactant.If you have a zeroth order reaction overall, then k will be equal to the rate. So if the reactants are consumed at a rate of 1.00 mol/liter/sec, then your k has a value of 1.00 mol/liter/sec. This means that no matter how much of the species you add, a lot or just enough, you will not change the rate.If you have a first order reaction where the concentration of A, [A] (in mols/liter), is consumed at a rate of .004 mol/liter/sec, then k = [A]/.004 mol/liter/sec, as given by the above equation: You divide the rate by the concentrations of the reactants. The units for a first order reaction are sec-1 or 1/sec, because you are dividing moles per liter by moles per liter per second. So the concentration of this does matter. The concentration of the reactant is proportional to the rate of reaction.If you have a second order reaction, then the addition of a reactant will increase the rate of reaction by a square of the concentration of the reactant. This is because you are now dividing the rate of reaction by, for example, [HNO3]2. Remember the the previous variables m, n, or p are the experimentally determined order of reactant. So a second order reaction results in squaring the concentration. Hope that helps!

The decomposition reaction of ammonia gas on platinum surface has a rate constant k equals 2.510-4 mol l-1s-1 what is the order of the reaction?
The rate constant is not indicative of the order of the reaction. To determine the order of the reaction, experimental data (such as concentration vs. rate data) is needed. The order of the reaction can be found by examining how changes in reactant concentrations affect the rate of the reaction.

What do you mean by specific reaction rate of a reaction?
The rate constant include all parameters ((but not concentration) affecting the rate of a chemical reaction.The expression "specific reaction rate" is used when the molar concentration of reactants is a unit.

If a temperature increase from 22.0 to 34.0 triples the rate constant for a reaction what is the value of the activation barrier for the reaction?
You can use the Arrhenius equation to solve for the activation energy barrier (Ea). The formula is k = A * exp(-Ea/RT), where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy barrier, R is the gas constant, and T is the temperature in Kelvin. Since the rate constant triples when the temperature increases from 22.0 to 34.0, you can set up two equations using the Arrhenius equation and solve for Ea.

What are the correct units for a second order rate constant?
The correct units for a second order rate constant are M^-1 * s^-1 or L/mol * s. These units represent the concentration change over time for a second-order reaction.
What is the rate constant of a reaction if rate 1 10 2 mol L s A is 2 M B is 3 M m 2 and n 1?
The rate law for this reaction is rate = k[A]^m[B]^n. From the given information, substituting the values for rate, [A], [B], and the exponents m and n, you can solve for the rate constant k. In this case, k = rate / ([A]^m[B]^n), so k = 2 / (10^2 * 3^1).

What is the rate of a reaction if the value of k is 3 and A and B are each 2M?
If the rate law for the reaction is given by rate = k[A]^m[B]^n, where m and n are the orders of the reactants A and B, respectively, then the rate of the reaction would be calculated as rate = k[A][B]. Plugging in the values given (k = 3, A = 2M, B = 2M), the rate of the reaction would be 3*(2)*(2) = 12 M/s.
