Kinetic equation, R=R∞{1-exp(-Kt)}

[Subhamoy Saha]

What is your question?

[Bharath KL]

I have a diffrent kinetics equctions, I know the values of the R, R∞, and t

how to put the values in matlab with code and how to plot the graph

Please help

It sounds like you may not be too familiar with using MATLAB at all.

If you need to get going quickly at using MATLAB I would highly recommend taking the time to complete the MATLAB On Ramp training

https://www.mathworks.com/learn/tutorials/matlab-onramp.html

Here's a general pattern that you could follow and modify.

Basically you need an expression to evaluate your rate, then you need to evaluate this expression for each point in time that is of interest, finally plot the results.

Just to give you a place to get started you could do something like this.

Rinf = 100; % put what it is in your situation
k = 10; % put what it is in your situation
tFinal = 5; % here final time is 1000 s, you could change according to your needs

% define a vector of time values where you want the rate evaluated
t = linspace(0,tFinal,100) 

% evaluate the rate equation for each time
R = Rinf*(1-exp(-k*t));

% plot the results
plot(t,R)
xlabel('time [s]')
ylabel('Rate')

Hi Jon, sorry I could not get you. The question acqually raised by Bharath KL and NOT by me. I was not sure what exactly the question was. Anyway I got the comment but not able to follow in time. Just saw it. Anyway thanks.

Hi Subhamoy, Sorry for the confusion. You are right Bharath was the original poster.

Bharath - did this answer your question? If so, when you have a chance, please accept the answer so that others will know that an answer is available.

[Bharath KL]

Sorry is wrong

[Bharath KL]

because I don't know the value of k, My quection is find the k value in this equaction
