First-Order Reaction Concentration Calculator

Calculate the concentration of a species in a first-order reaction using:
\[ [A]_t = [A]_0 \, e^{-kt} \]

* Enter the initial concentration, rate constant, and time.

Step 1: Enter Reaction Parameters

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

Example: 0.1 M

Rate Constant, \( k \) (s⁻¹):

Example: 0.01 s⁻¹

Time, \( t \) (s):

Example: 100 s
