function with vectors to calculate chemical concentration

Hi, I need some help with the a function that I need to write for a chemical exercise.

It has to be a function that calculates the concentration of the different elements depending on the time.

The function gets 4 parameters : starting_concentration, k1, k2, derivative and it returns the vectors of the different concentrations.

Two chemical reactions are given, the strating_concentration k1 and k2 are also given.

I have to define zero vectors which will include the concentration of each element of the reactions.

Each element of the vectors represents the concentration at a specific time (the vectors’ size is the number of times that we check).

Then I need to write a loop for each time t in order to calculate the difference between the previous and the current concentrations.

The codes that I already tried didn’t work at all and I am still a beginner so I would really appreciate your help and ideas.

Thanks in advance :)
