Differbetween
Summary – Reaction Rate vs Specific Rate Constant The key difference between reaction rate and specific rate constant is that reaction rate gives an indication of the speed at which the reactions are converted to products while specific rate constant is proportionality constant.

What is the difference between K and K in reaction kinetics?
If [S] is really big (i.e. [S] >> k-1 + k2), then d[P]/dt = k2 [Eo], which is effectively a zero-order reaction because k2 and [Eo] are both constant.

Summary of the differences between K and k:
| K | Little k |
|---|---|
| Thermodynamic, not kinetic | Kinetic, not thermodynamic |
What is specific reaction rate?
Specific Rate of Reaction or Rate Constant is the rate of reaction when the molar concentration of each of the reactants is unity.
What is rate constant k?
The specific rate constant (k) is the proportionality constant relating the rate of the reaction to the concentrations of reactants. The rate law and the specific rate constant for any chemical reaction must be determined experimentally. The value of the rate constant is temperature dependent.
How do you find the reverse reaction K?
The equilibrium expression written for a reaction written in the reverse direction is the reciprocal of the one for the forward reaction. K' is the constant for the reverse reaction and K is that of the forward reaction.

| Equation | Equilibrium Constant |
|---|---|
| N2(g) + O2(g) NO2(g) | Kc = 4.1 x 10-9 |
What is called specific rate constant?
The rate constant, or the specific rate constant, is the proportionality constant in the equation that expresses the relationship between the rate of a chemical reaction and the concentrations of the reacting substances.
What is chain reaction with example?
In chain reaction. Nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a preceding fission. For example, 21/2 neutrons on the average are released by the fission of each uranium-235 nucleus that absorbs a low-energy neutron.
What is the rate of reaction equal to specific reaction rate?
Answer. Hey. When concentration of each of the reactants is unity the rate of reaction equal to specific reaction rate .
How do you calculate rate constant k?
Zero-Order Reactions
- A zero-order reaction has a constant rate that is independent of the concentration of the reactant(s); the rate law is simply rate=k .
- rate=−d[A]dt=k.
- [A]=−kt.
- This is the integrated rate law for a zero-order reaction. Note that this equation has the form y=mx . ...
- 2NH3(g)→3H2(g)+N2(g)
What is K in 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 rate of reaction formula?
Reaction Order
| Zero-Order | Second-Order | |
|---|---|---|
| Rate Law | Rate= k | Rate= k[A]2 |
| Integrated Rate Law | [A]t= −kt+[A]0 | 1[A]t=−kt+1[A]0 |
| Units of Rate Constant (k): | molL−1s−1 | Lmol−1s−1 |
| Linear Plot to Determine (k): | [A] versus time | 1[A] versus time |
