The unit of rate constant of a first-order reaction is s-1.a)Trueb)Fal...
The rate constant (k) of a reaction is a proportionality constant that relates the rate of reaction to the concentrations of the reactants. It is specific to a particular reaction and temperature. The unit of the rate constant depends on the reaction order.

First-order reactions are those in which the rate of the reaction is directly proportional to the concentration of only one reactant. The rate equation for a first-order reaction can be written as:

Rate = k[A]

Where Rate is the rate of the reaction, k is the rate constant, and [A] is the concentration of the reactant A.

The unit of concentration is usually moles per liter (mol/L) or molarity (M). Therefore, the unit of the rate constant for a first-order reaction can be determined by substituting the units of Rate and [A] into the rate equation:

Rate = k[A]

mol/L/s = k * mol/L

mol/L/s = k

Thus, the unit of the rate constant for a first-order reaction is per second (s^-1). This means that the rate constant represents the fraction of reactant that reacts per unit time.

Therefore, the correct answer is option 'A' - True. The unit of the rate constant for a first-order reaction is s^-1.
