For a first order reaction A → Products, initial concentration of...
First order reactions are chemical reactions in which the rate of 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 reaction, k is the rate constant, and [A] is the concentration of reactant A.
The integrated rate equation for a first order reaction is:
ln([A]t/[A]0) = -kt
where [A]t is the concentration of reactant A at time t, [A]0 is the initial concentration of reactant A, k is the rate constant, and t is the time.
The half-life of a first order reaction can be calculated using the equation:
t1/2 = ln(2)/k
where t1/2 is the half-life of the reaction and k is the rate constant.
Overall, first order reactions follow exponential decay kinetics, meaning that the concentration of the reactant decreases exponentially over time. The rate of the reaction is directly proportional to the concentration of the reactant, and the half-life of the reaction remains constant regardless of the initial concentration of the reactant.

For a first order reaction A → Products, initial concentration of...
A → Products
Initial conc. A° = 0.1 M
Conc. After 5 min At = 0.001 M
t = 5 min.
For first order reaction
Initial conc. A° = 0.1 M
Conc. After 5 min At = 0.001 M
t = 5 min.
For first order reaction
