PotStep: Chrono amperometry with a finite step digital simulation

In EleChemr: Electrochemical Reactions Simulation

Description

Return a graph I vs t of the electrochemical process

Usage

PotStep(
  Co = 0.001,
  exptime = 1,
  Dx = 1e-05,
  Dm = 0.45,
  eta = 0,
  Temp = 298.15,
  n = 1,
  Area = 1,
  l = 100,
  DerApprox = 2,
  errCheck = FALSE,
  Method = "Euler"
)

Arguments

Co	bulk concentration expressed in Molar
exptime	experimental time to be simulated expressed in seconds
Dx	diffusion coefficient expressed in cm^2/s
Dm	simulation parameter, maximum 0.5 for explicit methods
eta	overpotential of the step expressed in Volt
Temp	temperature in kelvin
n	number of electrons involved in the process
Area	area of the electrode expressed in cm^2
l	number of time steps of the simulation
DerApprox	number of point for the approximation of the first derivative
errCheck	if true the function returns a list with parameters for CottrCheck function
Method	method to be used for the simulation = "Euler" "BI" "RK4" "CN" "BDF"

Value

if errCheck == F a graph I vs t, if errCheck == T a list

Examples

PotStep(Co = 0.001, exptime = 1, Dm =0.45, DerApprox = 2, errCheck = FALSE, Method = "Euler")
