FORTRAN programm for second order kinetics equation?

Answer 1

A simple FORTRAN program for modeling second-order kinetics can be structured to calculate the concentration of a reactant over time based on the equation ( \frac{1}{[A]} = kt + \frac{1}{[A]_0} ), where ([A]_0) is the initial concentration, (k) is the rate constant, and (t) is time. The program would prompt the user for initial concentration, rate constant, and the time period, then compute the concentration at that time and print the result. Here's a sample outline:

PROGRAM SecondOrderKinetics
  REAL :: A0, k, t, A, time
  PRINT *, 'Enter initial concentration [A0]:'
  READ *, A0
  PRINT *, 'Enter rate constant k:'
  READ *, k
  PRINT *, 'Enter time t:'
  READ *, t

  A = 1.0 / ((1.0 / A0) + k * t)
  PRINT *, 'Concentration at time t:', A
END PROGRAM SecondOrderKinetics

This program calculates and displays the concentration of the reactant after a specified time using the second-order kinetics equation.
