First-Order Reaction Concentration Calculator

First-Order Reaction Concentration Calculator

Calculate the concentration of a species in a first-order reaction using:
\[ [A] = [A]_0\,\exp(-kt) \]

* Enter the initial concentration [A]₀, the rate constant k (s⁻¹), and the time t (s).

Step 1: Enter Parameters

Initial Concentration, \( [A]_0 \) (mol/L):

Example: 1 mol/L

Rate Constant, \( k \) (s\(^{-1}\)):

Example: 0.1 s\(^{-1}\)

Time, \( t \) (s):

Example: 10 s
